DOA4:
one of the few games that i think beat tobal no2. and unlike other fighting games, it doesnt kill the action with shitty lighting explosions when you hit someone. (i hate that shit in tekken, hit int he face gets you a yellow/orange glob?!) and is all about style and pure brutality. it flows really, really well and doesnt rely on long ass fucking combos or juggles (mortal kombat anyone?) im sure some people like that shit but i dont. not since streetfighter. its always about open branch startegy combos than anything else. plus has the best grapple/throw/reverse system.
TES4: oblivion
one of the most unique realtime rpg's out there. period. its all good. but it has YET to be copied STILL till this day.. i dunno why... probably takes too much fucking work to knock off over at EA lol
