So for the Elder Scrolls Online, would you rather have preset classes or like in Oblivion you get to customize your own class? I know they said it will be like you choose a class when you create your character but personally i'd rather make my own to fit my style of game play.

I think we basically do make our own version of whatever class archetype we choose. We'll choose different weapons and level different skills, choose which of 3 stats to raise each level up, and maybe even wear different armour to the next guy, so your character could be totally different to my character even though we started out the same at character creation.
