Since nobody mentioned it. Exit 1&2 are super fun

I still have my PSP on my desk, on who knows how many battery replacements. I come back for:

• Burnout Legends
• Locoroco
• Lumines & Lumines II
• N+
• Echochrome
• Guilty Gear XX

Nobody mentioned Kingdom Hearts Birth By Sleep. That's pretty much kh1/2 off ps2 except on a handheld. Super cool and replayable game.

There's a disturbing lack of Phantasy Star Portable 1 & 2 in this thread.

Also want to second Rock Band Unplugged because it has similar gameplay to the ps2 game Amplitude.

Loco Roco was nice and I don't think its been mentioned.

PATA PATA PATA PON!

Brave Story is a great RPG that doesn't overstay it's welcome and that I've enjoyed a lot. The enemy design was what really got me into it at the time, but the fun story and quality of life features kept me going

LocoRoco, Patapon, the God of War priquel and Crisis Core

And also Armored Core Formula Front, it's such a weird game in the series.

Oh, and Carnage Heart EXA. I've never managed to actually get far, but it's the most unique mecha game there is. You program your mecha from scratch using logic blocks, and you can make it fully autonomous, fully manual (but you have to program each button press), or a combination of two. It takes as many hours to learn as an Armored Core game would take to complete.

Locoroco. It was just so sweet and cheerful.

I’m not going to lie even when it was brand new I thought the PSP’s graphics were lame for 3D games and never wanted one. But it might have been the prevalent art style.

I always had a great time with Field Commander. Before my PSP broke it was basically the only game I played.

SW:BF2 was also really nice because the autoaim made it a really nice power fantasy.

Well, there's no competition. It's Danganronpa.

Oh and the Parodius collection is also great.

I played Lumines so much I would see squares when I closed my eyes

Final Fantasy Dissidia duo decim and Crisis Core were the only games I really enjoyed on the PSP.

Original games - LocoRoco Midnight Carnival, Crisis Core Final Fantasy VII, Daxter, Trails in the Sky trilogy, LittleBigPlanet PSP, Silent Hill Origins, MGS Peace Walker, Gran Turismo... Remasters/ports: SMT Persona 2 Innocent Sin, Lunar SSSC, Breath of Fire III, Tales of Eternia (all of these games are JRPG, and all of them are the best version of these games in my opinion), Crazy Taxi, Prince of Persia games, Tomb Raider games...

Yeah, Monster Hunter Freedom Unite was probably also the game I spent most time on my PSP.

It depends in what games you Mike, but I loved Persona 3 Portable and Kingdom Hearts Birth by Sleep.
If you liked Monster Hunter, you could also try God Eater. It is a really gold Monster Hunter Like with a good story!

There are plenty of good titles already mentioned here so I'll go with something less popular.

• PangYa: Fantasy Golf - it's a golf game, as you can guess from the title. It has simple but really fun gameplay with customisable characters (outfits and equipment, the latter affects character stats). It also has a story mode to get you started.
• Puzzle Quest - RPG with match 3 gameplay for combat. Really addictive in a "just one more quest" kind of way.
• Ridge Racer 2 - it's Ridge Racer. Riiiiiidge Racer! Tons of content, bunch of modes, fun to control - it's great! Might be my favourite handheld racing game (and definitely one I spent the most time with). It's pretty much a celebration of the franchise until that point, especially the classic era.

Ratchet & Clank: Size Matters.

Played through that sucker more times than I care to admit to.

Jeanne D'Arc

A fantastic RPG.

• Fifa Streets
• Sims 2: I really liked the story mode of it where you had to solve different quests to ger your car back

• Field Commander
• Gran Turismo
• Grand Theft Auto Chinatown Wars (the best GTA)
• Hellboy The Science of Evil
• Jackass The Game
• Killzone Liberation
• Metal Gear Solid Portable Ops & Peace Walker
• Midnight Club LA Remix
• Motorstorm Arctic Edge
• Socom Fireteam Bravo 1-3
• Star Wars Battlefront Renegade Squadron
• Twisted Metal Head On
• Untold Legends Brotherhood of the Blade
• Worms Open Warfare 2
• Ys Seven

wipEout, Jeanne d'arc, Battlefront, locorocco, peace walker, Ys seven, Mega Man Powered Up, Gran Turismo, Dissida, Final Fantasy Tactics, Ghosts of Sparta

All the usual suspects are already mentioned, but I have to shout out one of the most unique and addictive strategy games I have ever played, What Did I Do to Deserve This, My Lord?

Crisis Core Dissidia Locoroco Lumines

And the vast catalog of PS1 games you could download from the PSN store.

Rengoku 2, I wish there was a modern game that could expand on the gameplay of it.
