I couldn't disagree more with your assessment.
First off, I feel your desired RPG actually restricts actual roleplaying.
In order to make a choice, you have to develop your good or evil side? Unless I'm misunderstanding you, that makes absolutely no sense what so ever. There is no realism in a system that requires me to reach a certain "level" in order to make a decision. Now, if I am inexperienced at something, I should -fail-, but I should always have the choice to do it. That is how Elder Scrolls works (yes, including Skyrim). I do agree that more consequence of action should return to the series (I.E. a guild won't accept you into their ranks if you do not have the appropriate skills they are looking for, and you cannot rise through their ranks until you become among the elite at those skill sets), but the fact of the matter, the choice is there.
Speaking of choice, I do not for a second believe that Skyrim is "simpler" or offers less choice than Morrowind.
Let's just take quest choices for instance.
Main Quest spoilers:
Spoiler The main quest of Skyrim gives you a very large moral choice regarding the issue of Paarthurnax. Do you slay him at the wishes of Delphine and Esbern? Or do you spare him, at the wishes of the Greybeards? Which side do you ally yourself with? Do you believe that Paarthurnax has redeemed himself? Or do you believe that he must die?
I have only played the main quest once, and I chose to spare Paarthurnax for roleplay purposes (my character would show mercy and forgiveness towards a soul who has chosen a path to redeem himself in life), so I cannot claim to know how the main quest differs if you choose the other option, but the fact of the matter is, you have a choice.
That one single choice is infinitely more choice than you have in Morrowind's main quest (and yes, unless my knowledge of math is completely off base - totally possible, I don't claim math to be my strong subject - the term "infinite" is accurate due to the fact that there is zero choice in the main quest of Morrowind).
More Main Quest spoilers:
Spoiler There is also the portion of the main quest where you have the peace conference between the Imperial Legion and the Stormcloaks at High Hrothgar, and there are multiple ways to deal with that meeting through your choice.
I would completely argue that there is more choice in the Skyrim main quest than in either Morrowind or Oblivion, which are both pretty linear main quests story wise. The big dynamic with Morrowind's main quest that makes it feel so non-linear is the fact that much of the main quest, you are told to go off and do your own thing for awhile, and come back when you are ready to proceed, while Oblivion and Skyrim both have a sense of urgency due to impending doom, whether due to an invasion of Daedra, or due to the destruction caused by the returning dragons. But story wise, Morrowind is very linear and offers little to no choice in how to proceed.
There is also plenty of choice in the Skyrim side quests as well. More spoilers:
Spoiler Off the top of my head, there is the quest in Whiterun of the Alik'r soldiers who are after the Redguard woman. You find her (Saadia), and she tells you her side of the story. And then you find the Alik'r leader, and listen to his side of the story, and you are put in the situation where you must determine who to believe, and make your choice accordingly.
And I know there are a few quests where people say that there is only "one way" to finish it, a way that doesn't really fit their character, but I argue that
is your choice, to simply not do the quest.
One more spoiler:
Spoiler "Innocence Lost" is one specifically that has gathered a lot of controversy, and while I too had my own issues with the quest, in the end, it really boiled down to - I did have the option to tell the child that I would not be his personal assassin, I did have the option to go investigate the orphanage for myself, and I did have the option to kill the head mistress or not. Have I "finished" the quest? Well, I guess that depends on how you view "finished". Officially, as in, recorded in my journal as "complete" and received the X-Box Live achievement for it? No. But I have finished it in regards to my character's involvement. My character has investigated the situation, and made his choice. My character is not a murderer, and thus, will not kill the head mistress. My character made the choice to leave the situation. As far as he, and I, are concerned, the quest is completed.
And
that is about the same level of choice that you have in Morrowind. You either do it, or you don't. And since Morrowind doesn't have a "completed quest" portion of the journal like Oblivion and Skyrim have, I guess it's easier for a player to feel like they RP'd finishing the quest, because, well, Oblivion and Skyrim still have the quests in the "active quests" section.
In terms of the quest arrows, I again 100% disagree. In Morrowind, when you received a quest, and were told a location to go to, the location popped up on your map as a big, bright map marker. You knew exactly where to go. The only difference was, you had to keep opening your map to find out which way you needed to go to get there, where Oblivion and Skyrim simply cut out the tedium and put the arrow on your compass telling you where to go. It doesn't really require any more brain power to find a quest location in Morrowind, it just takes extra needless, tedious activity.
As far as roleplaying goes, I feel that Skyrim offers a much better character development system than Morrowind or Oblivion. Morrowind and Oblivion are simply a 1-100 level system. You level up your skills, they go up in number, and you are more powerful. There's really no variety.
With Skyrim, there is the same 1-100 level system, but perks have been implemented, and the perks actually give you specialization. Perks make you have to choose. Instead of just grinding out 1-100, and being the same as every other character who maxes out those same skills, you actually have opportunities for specialization and customization by focusing on your perks to become more of a master in particular areas. I use this example often, but it's relevant, my friend and I are both playing dual wielding, Heavy Armor wearing warriors. And our characters are completely different. Why? Because of perking.
Now, Morrowind or Oblivion you could make yourself different via skill selection, and that is a big reason why our characters are so different. He wants to play a "pure" warrior with as little magic as possible, where as I want to heavily concentrate on my arcane abilities. But perks allow us to be different even beyond that. In Morrowind or Oblivion, once we max out our combat skills (in this case, One Handed and Heavy Armor), our characters would be totally identical in those skills. In Skyrim, however, even within those skills we are different. In One Handed, I have specialized in the Dual Wielding branches, as well as the Bladesman perk. In Heavy Armor, I am focusing only on the Juggernaut skill.
My friend, however, has specialized in the Dual Wielding branch just as I did, but he also invested in the one handed power attack tree. So while I'm running around chopping foes down with my dual wield power attacks, he's lopping their heads off in the process. He's more of a tank than I am, because he wears helmets (I wear hoods) and has a deeper investment into the Heavy Armor tree, thus having better armor capabilities than I do.
That investment that he put into One Handed and Heavy Armor that I didn't, I instead put it into skills like Conjuration, Alteration, and Enchanting. And even in those skills, I could have a totally different character than someone else.
I can be a 100 Conjuration character who specializes in reanimation and necromancy, while the next person who has 100 in Conjuration may specialize in Atronachs and Bound Weapons.
Back in Morrowind and Oblivion, a level 100 Conjuration character was the exact same as every other 100 Conjuration character. Less variety.
Skyrim offers more variety due to perks and specialization, thus, higher roleplay capabilities in my mind.
I do not believe for a second that Skyrim is any simpler than Morrowind. I truly believe that the tedium of Morrowind (and as much as I love that game, there are elements of it that are incredibly tedious) is confused with complexity and depth, and when Oblivion and Skyrim removed that tediousness, it was confused as "dumbing down", when in actuality, the same depth and complexity is still there, it just removes the unnecessarily obnoxious elements of it.
People blame the voice acting for the lack of in depth dialogue, but in reality, the dialogue in Morrowind wasn't in depth at all. There were no branching dialogue options, and tons and tons of the written dialogue was copy and pasted across every single NPC in the game. The only real unique dialogue was from quest related dialogue, and that quest related dialogue is no more in depth than what we get from the voice acting in Oblivion and Skyrim.
People claim that the quests in Morrowind were so complex and engaging, but they really weren't, so much of it was exactly what people complain about in Oblivion and Skyrim, which is "go to this dungeon, get this item, and bring it back to me".
People claim about simplifying the game, and "dumbing it down", but if anything, Skyrim is the game getting more complex when dungeons actually have puzzles that you need to figure out in order to progress through them. Granted, the puzzles may not always be the hardest things on the planet to figure out, but the fact is, there are actually puzzles that you need to figure out, and that's something that Morrowind never really had, and Oblivion had only in very small doses.
I just don't buy the argument that Skyrim is in any way "simpler" than Morrowind. I'm all for differing opinions, and I'm not upset by the fact that there are people out there that don't love Skyrim just as much as I do, but there are certain claims made about the game that I truly feel are objectively wrong. I really do feel that a lot of these claims either blatantly ignore the features and elements of the game, or are just completely ignorant to them.
