I mean, games I care about enough that I actually want to own them and play them. Maybe a half-dozen or so. Ten at best, if one includes the re-released FFs, and various Metal Gear and Syphon Filter titles.
Anyway, it's still a handheld system with a puny screen and an orphan media format - effectively a PS2 with a lot of the features stripped down. I can understand why others like it, but it's not for me. Especially not at the current high price.
