I never expected you to "Go B3YOND" of all people. not this soon anyone...
Well for single player i reccomend the following exclusives...
Folklore (Strongly Supported Add-On Content with Custom Content coming soon).
Heavenly Sword(Awesome but Short game).
Uncharted (Best looking game ever made).
Super Star Dust HD(The Crack of games that go's stale after-awhile).
WipeOut HD (Great Online to).
I suppose ELG would be good to but i think its exclusive to japan.
