[muyoso]

Just went through my game search phase a couple days ago. Notable standouts that run at WVGA and are absolutely awesome games.

Platinum Sudoku 2
Crayon Physics
Tower Wars (runs VGA, but nicely centered with black bars)
Pocket Uno (of course)
Experiment 13 (ridiculously fun game with full hardware acceleration)
Xtrakt (full hardware acceleration and awesome)
Tiki Towers (very fun)
South Park Imaginationland (haven't played it really at all, but full VGA and looks fun)
Risk (awesome full wvga)
Spore (looks cool, havent played it)
Asphalt 4 (racing game with full g sensor support)
Smartgear (NES emulator with support for other platforms)
