when i got my psp (which i didnt really want but it was free) i had no freakin clue what psp games were good so i did a bunch of reading and watching online. i would recommend checking the reviews at expotv.com, most of the reviews show actual gameplay footage so you can see what the game is like. i HATE watching game teasers/trailers b/c they are always misleading but the footage in the expotv reviews are of actual gameplays.
http://www.expotv.com/browse/reviews/Video-Games/Sony-PSP/197 theres the psp reviews but they have other systems too.
this review made me by hot shots golf for psp (was a huge hot shots fan anyway): http://www.expotv.com/videos/reviews/22/197/HotShotsGolfOpenTee/72332
