PSP Download suggestions

I'm thinking of downloading a game for my PSP, what should I get? I want a game with relatively low space (I've got around 900 Mb left) and lasts a long time. I was thinking puzzle quest or everyday shooter. Any suggestions? Thanks!PSP Download suggestions
If you were thinking puzzle quest, I say go for it. I have it on the DS, and it is great.PSP Download suggestions
echochrome! I got the download voucher and it's really fun and challenging. Plus there is a map creator to make your own puzzles.
I play a LOT of Super Stardust; the PS1 Crash Bandicoot games play very well on the PSP as well
i recently down loaded wild arms, its an RPG, and its pretty fun. check it out
Thanks! I already have echochrome-it makes my brain hurt...
