iPhone does have a lot of fun games, but besides Jewellust and the game emulators, Android IMO sucks for games at this time. A lot of devs are staying away until the install base of Android devices have more space to install apps.

G1 = 75 megs free space and the rest (including Droid) = 130 to 200 free megs of space. Considering a lot of the games are 8 megs installed and some of the better iPhone games are 20 megs or more installed, Android will not be too good for a while.
