I think of it as an Oblivion seleton with a more 'traditional' RPG leveling system, mad max-like theme, and matrix-like gunplay scenes (which haven't gotten old in the seven hours I've played.)

I bought the regular edition (special editions seem pointless to me) last night and haven't played much but already want to restart :P

(SPOILER) I agree, MILF that quest sounded pretty lamely built and it kind of depends on players being players... I hope to see less of that type of thing further on..
