Let's be honest here - Beth has one and only one goal - profit. That's it. And I'm not saying that there's anything wrong with that - I'm a minarchist/capitalist myself. But for precisely that reason - because I understand and value capitalism - I understand Beth's motives, and Beth's motives are purely, ultimately, profit.
Beth's profits are best served by appealing to as many people as possible. The path to appealing to as many people as possible with a video game is some combination of making it shiny and simple enough to appeal to and not frustrate rage quitters, but complex and challenging enough to impress self-styled serious gamers. So they are, completely understandably, trying to balance those two things.
How much of what is an expression of the former and how much of what is an expression of the latter is only really known inside their offices, and can only be guessed at by the rest of us, particularly without the game in hand. But it's an absolute certainty that both of those things are going on at the same time - to approach it any other way would simply be a bad business decision, and Beth didn't get where they are by making bad business decisions.
All I can really hope is that they manage to achieve a good balance of the two.
You're totally incorrect, yet sort of correct, depending on how you label it.
Bethesda Softworks (Zenimax) is only concerned with profits. They're the publisher, that's their business.
Bethesda Game Studios, the developers themselves, however, are not. There is many, easier and more profitable ventures in even game development (Hello Farmville raking in more than any AAA game ever released and costing around 14,000$ to create), if you expand a little more, there's so many other places the developers could use their skill set, and earn much more. If you're in the art of making games as a "Nine to Five" your studio is going to quickly sink to the bottom of the Mediocre Sea. Bethesda Game Studios is in the rare position of basically being the only developer with a near perfect track record (Valve also comes to mind) which gives them a lot more creative control than say, a studio that just got gobbled up by EA. If you believe for one second that "Profit" is at the forefront of the drive to create Skyrim, you are seriously beyond reconciliation with logic.
Now, unfortunately publisher and developer have to work together, because of the exponentially increasing initial investments that are being put into AAA class games. Much like film, sometimes this relationship is antagonistic. Occasionally however, it's symbiotic, as a group of investors can bankroll a project and bring otherwise impossible goals within reach of the artists themselves resulting in a better overall experience than the artists had even intended.
This is what gives games (And a lot of film) the classification of "Commercial art".
Now on to the question at hand.
Everyone's claiming "Dumbing Down" but I simply don't see it. What exactly is being dumbed down? Neither Arena, Daggerfall, Morrowind or Oblivion really had all that much going on under the hood. In terms of Character development, Skyrim looks to be the deepest of all. Daggerfall may have had a "Huge" (And boring) world to explore, but the world wasn't nearly as compelling as Morrowind. Morrowind may have had a compelling world, but the character development fell extremely short, even with the precious "Attributes" intact, Morrowind also suffers from a worse combat engine than Daggerfall. Oblivion fixed the Combat issues of Morrowind, bringing them back to Daggerfall status (albeit, better by virtue of technology), but the world seemed to have involuntarily inherited some of the dullness, while not having the sheer size of Daggerfall to compensate. Let's not even talk about Level Scaling.
Yet for Skyrim, if we take the developer's word for it. The Combat has become the most kinetic and visceral yet seen. The character development is taking on an entirely new level of depth that [potentially, won't know until we see a perk tree list] surpasses all of the previous games combined. A world that's will attempt to compel with less "OMG WORLD ENDING" and more political intrigue and contrast, and of course, no more Oblivion creature/loot(?) scaling.
So where exactly has Skyrim been dumbed down? At worst, sacrifice two weapon variants, and spellcrafting, which may or may not lend itself to the new magic system anyway? If you want to talk about "Dumbing down" go to the Mass Effect forums and sound off, that's where all the RPGers should be directing their rage.
I'm actually playing Morrowind Right now, and, at first I resisted kind of, negating the attributes, but now I really do see they are kind of pointless.
Strength (Carry Weight, Starting Health, Stamina, Weapon Damage) = Skill, Perks, Level up for additional Health/Stamina. Encumbrance(To Be Determined) Yes, it's pointless.
Endurance (Starting Health, Health per Level, Stamina) = Health Increase per level bonus. Stamina Increase per Level bonus. Yes, this is pointless.
Intelligence (Magicka) = Magicka bonus per level. This is actually
improved as no wizards no longer have a hardcap of pre-gear Magicka.
Speed (Movement Speed) = Encumbrance and Burden Based, or To Be Determined.
Willpower (Stamina, Magicka regeneration, Effect resistance) = Stamina bonus per level. Rest: Unkown.
Personality (Disposition) = Speechcraft skill and/or Perks. Useless.
Agility (Accuracy, Evasion, Stamina) = No more Dice Rolls. Stamina Bonus Per level. Useless.
Luck (Useless) = Modified Weapon properties such as Critical Hit rate. Tangible Improvement through Perks.
So as you can see, the only actual arguments stem from Speed and Willpower. Perhaps Strength as well, specifically for encumbrance. But most of the arguments are based on an absence of knowledge, and not any actual basis in what we know about the game.
