One thing which is a real pain is that to target different resolution Windows Mobile devices you need to create totally separate versions of a game with different gfx.
Most commercially released games for PPC actually scale up/down to suit the device automatically, is there any way this can be incorporated into the exported GE exe.
Additionally, it would be nice if the exported games could automatically switch to the correct screen format (landscape/portrait) if the device is not cirrently in this format.
