You're a good kid, Xen, and I like ya... so I've volunteered to take you under my wing and show you how psp gaming is done. FYI, watch the head on the doorway in. I hit myself god knows how many times with games people told me to get that I shouldn't have gotten. Anyway, I hope you're ready because here we go!

First and foremost: The tippy top tier

The best games I've ever played. Recently, I stopped looking at internet porn in favor of just playing patapon. Why? Because it gives the same orgasmic feeling and the climax never ends. (plus, I don't even have to take my pants off!!!)

Patapon 3 cums out in two days. Get it! or else...

Locoroco 1/2. Some of my favorite games period. Each one offers the player a wondrous experience with inventive level design, collectible items scattered across the levels secret areas in each level, and a highly amusing storyline & artstyle. I suggest you check this series out! or else...

Those games are all awesome aswell! Check them out... or/ you get the idea

EDIT: I forgot to mention Lumines and Prinny 1/2 plus Disgaea: Afternoon of Darkness (Do you like Disgaea?) <-- get those!

Second and almost foremost: Games that are awesome, but might not work well on handhelds for some (long titles FTW!)

1. God of War: Ghost of Sparta

2. God of War: Chains of Olympus

3. MGS5: Peace walker

4. FF7: Crisis Core

5. Wipeout PSP

6. Kingdom Hearts: Birth by sleep (Only if you REALLY like Kingdom Hearts)

That should get you off to a good start! Hope I helped

Patapon and the rest gave some really really good recomendations

I'll just mention one

VALKYRIA CHRONICLES 2! one of THE best games this gen for me

I wish that would drop a bit in price, everything else is under 40....why won't that... 

Resistace retribution

Syphoon filter: Logan shadow

Peace walker

Birth by sleep

God of war chains of olypis and ghost of sparta

dissida 12

Daxter

Final fantasy 1 and 2

ratchet and clank size matters

patapon 3(when it comes out)

Final fantay type 0

Monster hunter portable

valkyrie cronicles 2.

I would have paid $60 for the game...HONEST! that's how much I enjoyed it bar a cetain laughter (don't ask lol)..it's a long game too so it will last a while

Go get Valkyria Chronicles 2 right now or I'll never speak to you again >:

Major thanks everyone! And yeah, patapon, you did very much help ^^ one of the best recommendation post I saw yet.

Well Im gonna tell you wich great games I would buy (I also own)

God of war: Chains of the Olympus / Ghost of sparta

Final fantasy: Crisis Core

Metal Gear Solid: Peace Walker

and after you played everything just buy Monster Hunter freedom unite and then buy NGP :D

Patapon is dangerous every time i tried to play it i wanted to smash psp on the nearest wall out of frustration :) But then again i was always musically challanged ;)

Anyway make sure you get Tactics Ogre, VC2 and Jeanne d'arc. Three greatest gems in PSP library.

I'd stay away from most games based off PS3 franchises (LBP, Motorstorm, Resistance ect). In my opinion they're just vastly inferior versions of their PS3 counterparts with God of War being the only exception (I haven't played Peace Walker though so can't comment there).

VC2, Tactics Ogre, FFT: War of the Lions and Disgaea are all fantastic games and work very well on a portable system.

Pixel Junk Monsters is great fun too and can be very challenging!
