Like any of the Fallout games can prove, you can do perks and still have stats in the game, they are not mutually exclusive. Stats define your character physical and mental attributes, and affect the related skills in meaningful ways, while perks allow you to specialize by rewarding you with bonuses related to the skills you proficient at. They both allow for customization. Still don't see what are we gaining by getting rid of stats, and the need to do so.
You keep gleaning on perks when I said perks and other things. I don't see what you gain from keeping stats as the game has evolved from it's DOS origins. In Arena and Daggerfall they were incredible important and felt rewarding. Starting with Morrowind they became less important and in Oblivion they just seemed useless beyond Strength for Encumbrance, Endurance for health and Agility for Ranged damage. Now with the new incarnation of TES, Endurance is no longer needed anymore because of straight health increase. Agility is no longer needed because Ranged damage has been increased drastically to make Range damage more realistic and an equal force in the Combat Triangle. As for Strength, Encumbrance can be solved by many means including perks or building it into skills. People need to stop being pessimistic and try change. I know a lot of people are afraid of change but change is the natural order of all things and most of the time it is a good thing and I believe it will be for Skyrim as well.
Actually, if they did get rid of stats, there is no more strength for anyone, even that mighty nord warrior on the preview. Kind of odd? Its weird that Todd mentions that they want to make things a bit more realistic, at least in regards to combat, and they drop something that would make a big difference in the way someone would fight in real life. Skill should be very important, but a strong person should cause more damage that a weaker one when skills are the same, don you think?
I don't see how it is realistic for attributes either. Ok so I just leveled, I magically got beefier or smarter? Really? Now if you thought of it as you gain these things over the course of training your skills yes that would work but the same goes with the new system. You level skills and then your "attributes" that are no longer a points system still increase, they just aren't evident on the surface. I don't know why people feel the need to tweak their attributes when they make nearly no affect on the character in small amounts.
