Yeah there is (not in the original I don't think) but it isn't the skirmish mode I'm referring to.
In Company of Heroes (for example) I can play control points against the computer. Any match I can set up online against people, I can play against the computer.
You can't do that in Men of War. Their skirmish mode is something altogether different. That's what frustrates me about Men of War, which stinks because I love the game. If it had that kind of skirmish mode in it I think it would be the best WWII RTS game out there.
