Give me your guys essential psp games.

Give your guys essential psp games.

For the last couple if months I started playing more and getting more into Psp cuz of the vita emulator. I already owned a Psp but cuz I decided to only get physical games for ut my collection is small. Because of it I started using the vita emu to play more Psp games. I would like to hear what games you guys personally think everyone whit a psp should play. I only want psp games,I don't want ps 1 games cuz I already did a post on the PS1 subreddit asking for recomendacions. I want beside your normal classic responses your wierd, underrated, guilty pleasure or even just down right bad games.
