I like the older style games like Jagged Alliance 2, fallout 1 & 2, Dungeon Keeper, Final Fantasy 7 - 10 and the like. The only worth while games out today are Mass Effect 1 & 2 and GTA4 imo :\
It has the atmosphere of the true and original fallout games which is never a bad thing IMO, the quests are relatively interesting and I enjoy the combat. This is still in early access however so there will be further content and polish coming along and updates seem to come along at least once a month, also considering it's price I'd gladly recommend it.
