There are some very popular strategy games for consoles, Final Fantasy Tactics, Ogre Battle, Tactics Ogre, Disgaea 1 and 2, most nippon ichi games, and on the Game Boy and DS there are tons that work very well, mainly advaned wars and fire emblem, and some of the tactical RPGs from above have been adapted to the small screen.

The Nintendo DS with it's touch screen could be the perfect platform for Space Empires, the bottom screen is a "command" interface with a small keyboad, and the orders buttons you see in the lower right and across the top of the current screen,and a simplified system map(dots on a grid) where you can touch ships and move them, the buttons controll the map and system windows in the top screen.
