Well, everyone seems to be looking at the major "Console" platforms for porting.
(Xbox, Nintendo, etc..)
I'd like to see 3DGS (or a subset) ported to PocketPC devices.
Windows Mobile5/6 *does* include some DirectX drivers and D3D support.
Granted, you couldn't download a 50Mb game to one of these,
but I'm sure an enjoyable game could be written for these devices.
OK, maybe you *could* download a 50Mb game if you had an SDCard installed...
This could be a NEW market for distribution, and I guarantee you this market
is *not* saturated with 3D games!
Not to mention you wouldn't need *anyone's* approval to distribute your game
on these handheld devices.
