Nintendo DS

[AChimp]

The screen of a DS is smaller than that of a PocketPC. Age of Empires was converted so that it would run on Pocket PC 2003. The size of the sprites in AoE are about the same size as those in Starcraft.

AoE was virtually unplayable on the PocketPC because everything was so fucking tiny. Therefore, any good RTS would be virtually unplayable on a handheld console because everything is so small.
