Four words. Because Todd said so.
Didn't Todd say the same about the Oblivion level scaling too? How did that work out?
Also,
"Too much emphasis is being put on "skill" and basically the game doesn't acknowledge that some people may just be inherently better at some things than others due to the way they are born. It seems as if when you start off, all characters will be identical and will become more varied as you get into the higher levels. The latter of that is good, but seems most low level people in the game will be completely identical in their stats, skills, and usefulness, as if they were only "born" during character creation and never had a background. They addressed an issue both Oblivion and Morrowind had, but they introduced an equal and opposite issue in the process.
Characters should be different from each other at the beginning of the game, and be different from each other at the end as well. They've just reversed the issues. "
I want to expand upon this issue: I, in playing the game, want to make a character and then take that character on a journey. If everyone is a like at the beginning except for stamina/health/magica then, in my mind, you're saying everyone is equally ugly, equally stupid, equally weak, etc etc - everyone is essentially identical and this is a streamlined way for the attention-span limited to jump right into the game. I welcome perks/feats/etc which later flesh out my character but if playing through the game the only difference between my first character at Ug the massive Orc smasher and Mitzy the Barmaid who is joining the assassins is the single feat chosen at first level and the skills increasing/perks learned LATER on.. what kind of character have I made? Not much of one. Can anyone name a RPG that does not quantify the individual the player controls? Not their skills.. skills are things LEARNED. Attributes is a quantification of your natural beginning stuff.
