I've played quite a few real time strategy games but I usually get annoyed by how complex they are. I've never found one that was fun in multiplayer because the other players always had the advantage of knowing the game better than I did. That is, until now. Introversion have finally finished the multiplayer version of Darwinia and it is brilliant! So simple and easy to understand, yet with enough depth to be fun for a long time. A game usually last about a quarter of an hour and it's an awesome massacre! You have to try this game, I have never played anything like it. There is a demo available from http://www.multiwinia.com/ ! You can also get it on Steam if you want but at the Introversion store you can get it instantly without requiring Steam.
