This game has stillk a pretty active community, despite of being a 16 years old game. So I thought that maybe on the vast spaces of the interwebs there might be a good forum about this game where people discuss the series in all it's greatness.

This forum is decent but there are not many people online. Any hint where some people are still active. I tried to find some by using google, but the results were quite shit.

Thanks, I found that forum but I thought it was only for MoO3.

Although most topics are pretty old.

There is also the official Atari one but that's pretty quiet.
