I think this game could potentially be racist based on the representation of races/nations?
Anyway, it's a cute compact version of the RTS genre. I played the singleplayer exclusively which gave me a couple hours of fun but nothing too extensive. As everything else with AI there's a skirmish mode so you can just play a regular game against the AI.
I found some of the difficulty balance was a little off. Most levels were easy enough but the hard ones were extremely difficult. There were only one or two of those, though.
Overall I had a good amount of fun with the singleplayer. It began to become a little repetitive after a while as some missions were just "kill the other guys" but I'd recommend it to anyone who is interested in playing it.
