Mha ha ha, I thought it might take me a while to find the games I listed before for PSP given that they're older games, but it's actually much easier and cheaper than I anticipated.

For now, my PSP game library has grown to a total of 3 titles:
- LittleBigPlanet
- LocoRoco 2
- Patapon 2

Except for the original LocoRoco and Patapon, I'm pretty much set for English PSP games. Now I just need to find myself some Japanese games...
