What PSP games should I get?

I'm getting my PSP repaired . I already have Namco Battle Museum Collection, Wipeout Pure, NBA Live 08, Daxter, and Joanne D'arc. I like platforming games, racing games, RPG's, tactical games (somewhat), and arcade games, and fighting games. What ones should I get?

I recently bought a PSP because of the game Crisis Core I bought quite a few other games with it as well and an 8 GB card. I was a lot more impressed with it than I thought I would be of course as soon as I bought it I read the 3000 was being released which is kind of typical but still it was worth the money.

But the Games I bought with it are

Grand Theft Auto Vice City Stories
Grand Theft Liberty City Stories
Crisis Cross
Tom Clancys Rainbow Six Vegas
Medal Of Honor Heroes 2
Wipeout Pulse
God of War
Ridge Racer
Test Drive Unlimited
Capcom Classics Collection Reloaded
Football Manager 2008

Of those ones the most Impressive is probably God of War Chains of Olympus and Crisis Cross. The one I've been playing the most though is Vice City Stories and the only one I've been disappointed with is Rainbow six Vegas.
