Mine was Burn Zombie Burn. I haven't played it in awhile as well. I need to platinum RE5 first before I got back to that game. 

None, because the assholes at Sony wont let me use PSN since i bought my PSP used

That sheep hearding game.
forget its name

but decent

alos got flower, awesome

and echochrome thingy,  not so good.

Hmm? Are you sure? I think you can make a new account on the website and login with that? Or something along those lines... PSN accounts don't actually ask for console serials and what not nowadays, do they? The last game I bought was Burnout, not the latest game, the older one. I forget the title atm. I wanted to buy stuff like Symphony of the Night but they're not available in Europe. Gah.

Flower

None, Sony doesn't want my money (aka I don't have a CC).

I have to have the PSP on the latest firmware version to download PSN games, and i cant get the latest firmware thanks to the previous owner of my device"

Prince of Persia Epilogue if that counts.

i havent bought one yet but Trine looks really good

You can't update the firmware? How come? Surely any homebrew stuff or custom firmware can be reverted to default somehow, so you can update? Or at least get some custom firmware that uses the latest official as a base and access the store? I don't know much about PSP (despite owning one, since I never homebrewed it) but I don't think homebrew stuff would be so popular if they stopped you from doing basic things like visiting the store :S

I bought both Noby Noby Boy and flower on the same day. Great titles, by the way.

So, look into it than have a gimped PSP? Ask your friend what crap he did to it, then go in some related forum and ask how to update. Someone somewhere will be helpful... Better to take 10 mins for that than stay with a gimped PSP for good... Still, sounds like Sony isn't to blame here.

Flower, and my next one will probably be MvC2

Everyday shooter.

Flower. 

With my next one planning to be Fat Princess.

I got Pain for free with my 160gb ps3, I'm thinking about getting Flower.

Noby Noby Boy. Fat Princess is next.

Flower, and my next one is Fat Princess :D

None because PSN sucks /end
I'm waiting for Fat Princess

Super Street Fighter 2 Turbo HD Remix it seems... and before that: Noby Noby Boy

The Sony rep that got back to me essentially said that PSPs that have used homebrew programs wont be able to use firmware updates

"

Noby Nobs

None, first will be Fat Princess unless I cave in and buy Flock cause the demo was quite fun.

Also isn't most stuff with a PSP done with the battery or something? Never tried to mod my PSP.

"I bought both Noby Noby Boy and flower on the same day. Great titles, by the way."

Mine was Jeanne d'Arc.

I bought Noby Noby Boy last, with Flower being my first.

"Mine was Burn Zombie Burn. I haven't played it in awhile as well. I need to platinum RE5 first before I got back to that game. "

Nothing as of yet. I got a voucher to get Pain for free though if I use it before the end of next week. So I guess that'll be the first. Because free is awesome.

Noby Noby Boy. Now I'm waiting for Fat Princess :D

I got worms, very enjoyable as I am an old fan.

Last game i bought was Flower & Burnout Paradise

Last was Burn Zombie Burn. Next will be Fat Princess.

None yet, It seems that it would only make me throw away money for trashy games. Until something comes along that i absolutely must have im not investing in PSN.

Noby Noby Boy was my most recent purchase,  but MVC2 will be tempting...
