If you like RPGs then get a fucking 360.
If you like action games, then get a fucking 360.
If you like multiplayer games... GET A FUCKING 360.
If you like waiting for good games to come out, buy a ps3.
This is so fucking true.
However, I would still consider getting a PSP. If you're really into RPG's, you have a ton to choose from.
1. Final Fantasy Tactics Remake(good for a remake)
2. Crisis Core
3. Star Ocean
4. Final Fantasy 1 & 2(another good remake)
5. Brave Story, which sounds like THE GAME for you to get. I have a feeling you would love it.
6. Valkyrie Profile
7. 1000 + Roms, emulators, etc if you mod.
While more than half the list are of remakes of games already released, they still hold their own, especially on a handheld.
You can wait for the PSP though, and if you're looking for something to get right now, I think the 360 would be the way to go. They have the same selection as the PS3, and more. I still don't think Metal Gear Solid or any other exclusives can save the PS3, but with the recent price drop of the console...MAYBE.
