What Skyrim is trying to do with how players approach their desired character is totally different with morrowind and oblivion. The most obvious change is the attributes.
There are more viable reasons that attributes are out than trying to make the game more appealing to newbs or those who want everything simple.
First they wanted to introduce perks. Perks are tied with skills. If attributes like strength or agility that affects weapon damage as well as one handed or archery skill perks would comparatively lose its importance. I said comparatively because some argue that Beth could've just fixed attributes not rid of them and still introduce perks. This argument is redundant because by taking out the attributes they can stress the importance of perks, the new feature in Skyrim. It is easy to understand that having attributes+skills+perks is not a simple addition to having skills+perks. They're NOT 'bigger than' relations. They're just 'not equal'.
Second, since perks are tied with skills, we can safely say that skills more or less govern the entire character's performance. In previous series of ES attributes increase reflected how much your character spent time with a group of skills. A character with high strength could've spent more time with blade, blunt or hand to hand, but didn't particularly reflect a single spell. Thus a guy who ignored blade completely and only practiced blunt got better at blade cause blunt raises strenghth. Now I'm not saying this is wrong. It is natural that a guy good with blunt can get better with blade more than a guy who only practiced magic. It makes sense and I agree BUT a game design is not about making sense. It's about how players can interact with the game in meaningful way. Now that skills are the only governing aspect of a player's performance what is reflected in your character's growth is only consisted with what your character actually did in the past. Compared to previous series Skyrim character is a stronger representation of 'you are what you do', and this is what Skyrim is meant to be.
Skyrim is just a different game with different purpose in game design. There's no reason to deny it or criticize it.
Wow, I couldn't agree more with something. In the end, these "attributes" are nothing more than "perks" gained through bettering your "skills". It's not about the realism of the names and mechanics of the system, it's the feel of how it plays within the game. Your time is the experience points and as opposed to putting them into things that should naturally get better from your actions, they cut the middle man out so your "strength" or "willpower" increases with the increase in your time put into that certain skill. Never before has this been done in this way other than in TES and if it plays out how they've led me to believe, we are faced with a revolutionary step in a levelling system that hasn't quite been perfected in TES series(oblivion's levelling system was clunky and forced you to play out of your desired playstyle to maximize your "attributes") but has always been at the forefront of it. Cutting out the numbers and lists and giving you that feel that the body of your PC naturally reflects what you do isn't simplification, it's amazing.
When thinking of how we actually interact with our skills in real life, perks in our skills are really closer to the reality of the fruit of our actions. When you practice a skill, let's say basketball for easy example, through your efforts your body naturally becomes more agile, stronger, or tougher depending on your position and strategy of play. Also, as you play you begin to pickup certain techniques, raising your skill to a higher level because of it. These gains in the attributes along with the "moves" list of techniques gained are a lot like how I feel the system in Skyrim will play out. It will feel more natural than any title to date. Certainly, you will lose the "depth" of the attributes lost, but you sacrifice those clunky numbers for a more natural feeling system. It unlocks the doorway to a more natural system, that in time, will grow deeper in depth...if you just let it be. Attributes will come back, as soon as they find a better way to implement them.
