Technically, it was the Metal Gear Solid: Peace Walker Big Boss Pack PSP. Set me back 200$.
[HEADING=1]Worth Every Loli-Damn Penny.

EDIT: Runners up are the Prestige Editions of Call of Duty: Modern This Is A Crappy Game And A Waste Of 150$ 2 And Call of Duty: Black Ops.
Blops was worth it. MW2 was worth it only for Call of Duty: Classic 1 month ahead of release, the NVGs and the art booklet.
Blops... well, Zombies and an RCXD. Hate the killstreak, Love the car.
