Fine, I'll just list.
Get King of Fighters XI, Melty Blood: Act Candenza, and Garou: Mark of the Wolves. All of those are phenomenal fighting games. Also look into the Gunstar Heroes Treasure Box which has Gunstar Heroes, Alien Soldier, and Dynamite Headdy included.
There's quite a few more to add if you're into shmups, but I don't know if you are so I'll dodge that for now.
Oh, and if you like RPGs... and I mean eally like RPGs, maybe get Final Fantasy X International. It's an updated version of FFX and it's entirely in English. It's got more bosses, dark aeons, new sphere grid stuff, etc. Maybe I'm the only person weird enough to blow insane amounts of cash on it though.
