Hm. Well I still stand by my statement that Mega Man Powered Up is the best game on the system. That counts as a shooter (you shoot dammit). Also, by the traditional definition of shooter Metal Slug Collection and Gradius Collection ($10 at TRU) are both worthy pick ups offering a ton of bang for your buck. Metal Gear Portable Ops is a fantasic game as well, and many like Killzone (not my cup of tea though). As far as sports games go, the vast majority of them are similar to their PS2 counterparts. If you like Madden on the PS2, you'll like portable Madden on the PSP and so forth. Virtua Tennis: World Tour is a competent port of Tennis 2K2 (ignore the oldness of the game, it's great) from the Dreamcast that I enjoy a lot too. Hope that helps some.
