I should get Sin & Punishment one of these days...And I'll probably pick up Rearmed next week. I'd have done it today but I wound up jumping at Gamestop's 25%-off sale on some PSP titles.
P.S. I also have the Homebrew Channel, which of course lets me, *ahem*, bridge some deficiencies, but I still buy what I've waited for as it comes up. A tool I may be, but a guiltless one.
EDIT: Forgot Yoshi. A little sad, seeing as I may be the only person I know on the Eastern Seaboard that enjoys it.
