What happened to the series...
There are increasingly fewer guilds with any sort of competing interests. The guilds that remain are shallow and the top rank can be achieved with minimal effort. For example Morrowind had skill requirements to advance to the top. Why can a hack and slash barbarian become the leader of the College of Winterhold by completing a few insipid linear dungeons? Even if Oblivion's guild quests were mostly boring (exception Dark Brotherhood) at least they had content and semi-realistic progression. With Skyrim I feel like the guilds serve no actual function.
Forget any notion of increased realism/depth. For example, an unreasonable amount of non-player characters are unable to be killed. I mean seriously what happened to consequences for your actions? Weapons and armor don't decay. There are no custom spells. Every quest tells you exactly where to go and holds an arrow over the head of the objective. I can't get into a game where there is a magic arrow that marks every target. Each game in the series progressively gets fewer weapon and armor choices. And don't argue adding a few mini-games creates immersion. They aren't even skill based, for example why would a character with 15 in smithing be able to create a flawless item every time. You can have smithing maxed out in a few hours, what a complete joke. And the removal of attributes in favor of perks is clearly a ploy to cater to the COD crowd. Though not necessarily the idea of perks just the way it was implemented.
Then there is the fact that the lore of each province since Morrowind has seemed shallower and uninspired. Nords or some variant are the cornerstone of nearly every fantasy universe and there is literally nothing unique about Skyrim and Nordic culture in comparison to most generic fantasy universes.
In conclusion call it streamlining and justify it any way you want, but the Elder Scrolls of the past was about simulating another world where anything was possible. Skyrim is one huge step backwards and you can boast of merits through its rave reviews, records sales, and mountains of cash generated but time will be its ultimate judge.
For the most part, i agree with whats said here. The guild design since Morrwind has been rubbish. You can become Archmage in Oblivion without casting a single spell, and in Skyrim, you can get there with a whopping repitoir of 2 spells. The reliance on internal, world shattering storylines is anot far, far too over the top. Does the world need to be under threat from the Daedra, Hist crazy mercs AND the King of Worms at the same time? Skyrim isn't much better, what with the Eye of Magnus, the closing of the Ebonmere and the Assassination of the Emperor, on top of the return of the dragons. Too many world changing events all at once dilutes the importance of each.
I also agree with the Lore thing, but to a lesser extent. There is still some of the beloved esestential nonsense and mythos in Skyrim, more in fact than in Oblivion, which was basicly a textbook Demonic invasion. Paarthunax is himself something of a Vivec junior. Still, i would like to see more books, since i think asking for in-story elements is a lost cause in a voice acted open ended sandbox. We'll see what Bioware can pull off with DAIII, see if the same depth of conversation is possible in a Skyrim style game.
Finally, i agree that 'essential' characters should go. I remember in Morrowind, i watched my brother murder Cassius Coscades, and a box appeared at the bottom of the screen telling him he was now unable to finish the main story. THAT is the extent to which characters should be essential. If someone blunders and kills them, let them reload and not make the same mistake, dont deny them the ability to kill someone.
I do dissagree, however, that the removal of atributes and the switch to perks is catering to the COD crowd. I think it is the logical progression into a less spread-sheet based RPG, something which i completely endorse. With some refining, the Perk system could bring back many of the old 'skills' which we lost as specialisations and radically increase the number of potential character builds we've seen. As it was, if you played Oblivion or Morrowind long enough, every character would turn out the same. All skills at 100, all stats at 100. The only unique atribute was your birthsign. There is absolutely no way, short of cheating, to get all the perks. This means it has infinately more individuality than the old system had.
All and all, i would say TES has grown. Rare is the person who keeps all their childhood friends when they grow up.
