good games for my new psp 3000?

ok i am new to psp and i got one but i have no idea what games to get i cheked god of war but my strict parents said no but i am a psp noob so chould you guys give me some of the best psp games as well as some online psp games thank you very much

I would say manhunt but its way more violent than god of war..

Maverick Hunter X is good if you like a old school side scroller , Kingdom of Paradise is a very solid RPG and finally my beloved The Warriors a great beat'em up...

I really dont use my psp for online gaming but I heard great things about Resistance Retribution mp..
