I am interested by what they offer - that your character should not have a pre-set class with chosen skills, but rather should evolve as you, well, act. Feels right. What with the bonus for specialization (better levelling if you up skills that high) and the hopefully many, varied and interesting perks, it should prove to be interesting.
I do have a tinge of nostalgia for the classes, though. It's a kind of identity thing.
Anyway, as usual, I will end up as a stealthy character - short blade, light armour, lock-picking, sneaking around, and so forth. Never bothered to learn much magic beyond your basic emergency restoration spell, maybe I'll dabble a bit more this time around. That dual wielding thing promises to make it worth experimenting.
