The skill and attribute system has been rethought to make it more streamlined yet offer much more varied character builds. We’re down from 8 attributes and 21 skills to 3 attributes and 18 skills, which will probably cause gasps of horror in some camps, but actually the aim is to make character builds even more diverse while getting rid of redundant levelling.Acrobatics is gone, for instance – “who makes a character that is like ‘I am someone who doesn’t run?” Each skill unlocks a series of perks, which add multiple new abilities – such as a slow-time mode for arrow shooting. Each perk has certain requirements, not purely having unlocked the one below it. “You see a perk you like and say ‘I’m going to start using my sword more because I want that perk”, says Howard. The attributes, meanwhile, are distilled to Health, Magicka and Stamina. “What we found was those [old] attributes actually did something else. For instance, Intelligence just affected Magicka. They all trickled down to some other stat.” Again- this will cause gasps of horror. Maybe those will be justified, maybe they won’t – we won’t know until we play. Conceptually speaking, however, I dig the idea of your character build now being more about your actions than about strict segmenting into what were in some cases multiple attributes with similar effects. It does mean it’s more a game of actions than of numbers, and that’s always going to get backs up, but in this instance I’m fairly sure they’ve genuinely done it to increase engagement with your character and what he/she/it gets up to than to stoooopidise matters.
This was taken from an article, I remember reading it too. It contains a statement from Todd, which you can (AGAIN) refer to that.
And everything I've written above is based on things we already know about Oblivion and things we know will be in Cyrodiil, no speculation, nothing like that, just pure flat out FACT. Deal with it.
EDIT: Man, there are even quotes from Todd Howard there that say "Says Howard"......
