I suggest renting Heavy Rain for now....I'm pretty sure they'll release a GOTY edition close to the end of this year with all the DLC content included in the price. It is just me or developers love to do that now a days...I suggest NGS series...I'm sure you can find both of them at sears for like $20 each (of course YMMV and its well worth the drive to get 'em). Also, I recommend Tekken 6.
EDIT: Whoops looks like the above poster already mentioned that lol
