With war games it has pretty much come down to one question for me: Is the AI any good? If it is not, then none of the other features matter. So is the Warplan AI good?
It's merely meh so far. But the developer is working on it.
Hard question to answer. Good, bad or somewhere in between is subjective and as much depends on the skill of the player as the competence of the AI. On these forums I have always felt skill-handicapped. Games that some post as brain-dead,( i.e. many of the Tiller games), I find to be quite challenging. That said, I have found the Warplan AI interesting. It seems to be built around the player being the Axis rather than the Allies. But all in all, for me, still puts up a challenge.
