Other then GOD OF WAR/FF7/SYPHON FILTER/GTA GAMES(already got all those on Black Friday)

What else is good? :confused:

Patapon
Puzzle Quest
Echochrome
any PSX games you have via Remote Play (assuming you have a PS3)

Pirates! - brilliant port of the PC classic. Sail the seas, marry, trade, hunt down pirates, manage your crew. It's an open-world sandbox. A must buy IMO, but out of print.

Final Fantasy Tactics/Disgaea - both games are really awesome SRPGs. Can't go wrong with either one.

Castlevania - the first US release of the PC Engine game "Rondo of Blood", generally considered the best Castlevania. It also includes SOTN as an unlockable.

Mega Man Powered Up/Maverick Hunter X - Powered Up is a full remake of the first Mega Man (for the NES), while MHX is a less comprehensive version of Mega Man X (on the SNES). Both are great, but challenging games.

Pirates! - brilliant port of the PC classic. Sail the seas, marry, trade, hunt down pirates, manage your crew. It's an open-world sandbox. A must buy IMO, but out of print.

Could not agree more, love that game, I just wish it had the "Hall Of Fame" that keeps all your top scores.

Buzz is another good one.

Patapon (mentioned before)

SmackDown vs RAW 2009
Pursuit Force and Pursuit Force 2

Jeanne d'Arc
Metal Gear Acid
Killzone

I can't stop playing Lumines.

Dead Head Fred, Metal Gear Ac!d 1/2

the sega genesis collection is good, also hot shots open tee

Heard good things about Monster Hunter.

Crush - very cool 2D/3D puzzle game last year

Madden 09!

Pirates!
Lumines
MLB The Show
God of War

Riiiiidge Racer!

Seriously, that is still one of my favorite PSP games. The controls aren't realistic and the AI is rubber-band, but the car and track selection, soundtrack, and visuals are all great. I had a lot of fun with it, and since it was a launch game it's ridiculously cheap right now.

I'd also recommend Wipeout Pure (or Pulse if yer nasty). Lumines and Disgaea are must-buys if you like those types of games.

Jeanne 'd Arc
Final Fantasy I and II (the 20th anniversary remasters)
Locoroco
Patapon
Lumines
Wipeout(s)

Ratchet and Clank: Size Matters
Brave Story: New Traveller (if you like turn-based RPGs)

surprised no-one has said Metal Gear Solid Portable Ops.Street Fighter Alpha 3 max is a faithful port but some of the special moves can be difficult to pull off with the PSP control nub.

Crush is the only game that has ever been in my PSP for longer than 10 minutes.

Hot Shots Golf 1 or 2.

PlayStation Store just lit up a few titles for PSP.

Yes. Everyday Shooter and Super Stardust are no-brainers.
