Just tried the demo...

[Marmoset]

Hi, just tried the demo, and thought it was pretty fun. One thing I agree with the original poster on is that the AI is pretty weak. I was wondering if the gold version has (or you've thought about adding) a handicap system. While making the AI a lot tougher might be hard, it might be easy to artificially make it tougher by giving its units bonuses (such as more hit points, cheaper, etc). This could go a long way towards making the AI skirmishes more fun...
