I get a good amount of games on release date, but there's some I hold off on, especially huge publisher AAA titles (EA, Ubisoft, etc) that I know will be easy to find in several months and will have a ton of copies printed. If its a game that looks interesting to me but not enough to make me pay full price and I know it will be super easy to find later, I hold off, unless its something I really, really want (recent examples include Dead Space 2 and Bulletstorm). There's also certain titles and developers that I always pick up on day one, like Atlus, Nippon Ichi, Vanillaware, Tri-Ace, and any Silent Hill, Metal Gear Solid, or Castlevania game. Like K-Man, I have Atlus syndrome and I always pick up their games on release date or within a few days after and a good chunk of my backlog consists of their games.
