psp games

Shin Megami Tensei: Persona 3 Portable

Dissidia, Tekken

Also got a PSP but not too many games. I'd recommend Monster Hunter Freedom Unite and Harvest Moon Hero of Leaf Valley.

3rd Birthday or Metal Gear Solid Peace Walker, hands down two best games on the platform

the 2 god of war titles

Vice City Stories and Liberty City Stories.

Huge list of games here

Try fat princess fistful of cake for a refreshing indie experience. It's an action and real-time strategy hybrid that delivers endless hours of fun (story + objective-based modes). I myself have played it for very long

If you like Jrpg's any Tales of __ game, they last for hours and the story is usually nice.

First of all, make sure you install custom firmware so that you can play emulators. Sony "ported" a lot of PS1 games over to the PSP, but it wasn't long before the modding/hacking/custom firmware-ing/what the hell ever you want to call it community found out that these weren't actually ports, but rather the new PSP firmware had a built in PS1 emulator. Basically, for the most part it's a perfect PS1 emulator, but unless you unlock it, you only have access to the handful of games Sony officially sold. With custom firmware, you can just rip (or pirate, if that's your thing) .isos of PS1 games and convert them to the .pbp format and bam, PS1 games in your hands.

There's also emulators for classic systems like NES, SNES, GBA, Genesis, and even a few nowhere-near-perfect N64 and DS emulators.

With all that said, despite the PSP being pretty much devoid of decent games for years, it ended up with quite a good library. Some suggestions:

• Tactics Ogre: Let Us Cling Together
• Crisis Core: Final Fantasy VII
• Final Fantasy Tactics: The War of the Lions (enhanced version of the original PS1 version with a couple new characters. Suffers from lag not present in the original and the translation is in parts a classic case of "It wasn't broken, why oh why did you 'fix' it?" You may want to just emulate the original. shrug)
• Lumines/Lumines II
• Mega Man Powered Up
• Metal Gear Ac!d (Card battle game, not for everyone but I had fun with it. There was a sequel that I didn't end up playing).

I wish I could tell you more but I'm working from memory here. My PSP stopped working about a year and a half ago (honestly if I reinstalled the firmware it'd probably work just fine but I haven't gotten around to it yet). Also, ultimately the bulk of my time on the PSP ended up being used to play emulated games (like a maxed-time save file on Final Fantasy VII, perfect runs of every playable Zelda game, 100% runs of Super Metroid, etc.)

EDIT: I'd also like to second suggestions for some games I forgot about like both Dissidia games (if you're in it for the story, get both, otherwise get only Duodecim) as well as the GTA games.

PSP Revolution (homebrew)
Rock Band Unplugged
Crisis Core

Disgaea, all of them.

Echoshift

Ys Seven
The most fun I have ever had on PSP.

Dissidia Duodecim
Best fighting game on the console, so much fun, also have the full story of the first game in it.

What Did I Do To Deserve This, My Lord? 2
Fun as hell little game. Also includes the full first game, instruction book tells you how to access it.

Persona 3 Portable
Handheld Port of Persona 3, with some extra goodies!

Brave Story: New Traveler
Amazing RPG, give it a try!

Riviera: The Promised Land
This is a not-very-well-known gem in the PSP library. Originally released on the GBA and remastered for PSP, it offers a unique experience. Great story, great characters, amazing soundtrack. If you ever find it, nab it quick!

Final Fantasy IV: Complete Collection
Includes Final Fantasy IV, Final Fantasy IV: Interlude, and Final Fantasy IV: The After Years. Hands down my favorite game of all time.

Katamari!!1

SOCOM games, WWE games, GTA games.

can't believe noone mentioned corpse party yet. Play it. It's absolutely awesome.

Kingdom Hearts Birth By Sleep. Being a prequel to part 1, you don't need knowledge of any of the other games. It's an action adventure game that plays quite a bit like Final Fantasy: Crisis Core (which has been suggested above). I highly recommend it.

Fortix :D
(not kidding)

Dungeon Hunter

Castlevania: The Dracula X Chronicles, Has the remake of Rondo of Blood, the original version of Rondo of Blood and Symphony of the Night. You would probably enjoy it.

If you are a fan of the Final Fantasy series, get the Final Fantasy 4 Complete Collection. It's got the original Final Fantasy 4, All of the episodes from Final Fantasy 4: The After Years and even a new game called Final Fantasy 4 Interlude, which ties in between Final Fantasy 4 and Final Fantasy After Years.

There's also Persona 1 and 2 (Innocent Sin, the PSP remake of Eternal Punishment never came out of Japan so the only way to play it to buy it on the PSN store and download it on the PS3)

Hope this list helps you.

Valkyria Chronicles 2. The story and characters may seem a bit too anime-ish, but the game is great. The 3rd one has a fan translation, but I haven't played it yet.

If you like tough 2D action platformers and/or the Disgaea series try Prinny: Can I Really Be the Hero?

GTA China Town Wars. Not only one of the best games on the platform but imo, one of the best GTA game.
Daxter is also nice, God of War games (look great on it), Burnout Legends, Monster Hunter, etc. There are alot of good titles for it imo.

Danganronpa is really good
