SunAge is a terrible RTS, lacking definition, originality, or fun, wrapped in a half-arsed story. Don't even think about it. The graphics are a bland, sub-Red Alert 2 affair, but the gameplay falls further into the depths of mediocrity. The UI is clunky, travelling into the past with some kind of horrible mishmash of Total Annihilation and the original Command & Conquer.
Controlling your army is worse still, forcing you to select only a few troops at a time, moving them in separate groups. The icing on the cake is the abomination of AI that requires your troops to be in range to attack - don't try and click on an enemy to have your troops move into range - it won't happen.
