I recently got myself to buy this game when Corsair showed me some videos of it. It's a large scale futuristic RTS from 2007, featuring some really neat concepts like zooming out until the game looks like a map, while also being able to zoom in and watch single units duke it out. Another cool feature are enormous units called experimentals, think 100 meter tall robots with big lasers. It allows for many types of strategies and plays and gathering information about what your enemy is going for is essential, as there are dozens of ways to mess you up, each requiring its own counter.
All in all a really interesting multiplayer RTS that has grabbed me and I want to share the love. The official multiplayer servers have been taken down, but there is a decently sized dedicated community which has created a really neat multiplayer client called Forged Alliance Forever which works very smoothly. They have further balanced the game and are actually developing a Strategus esque factional war thingy. There are probably a few hundred people playing on weeknights with about 12 lobbies open at all time, but as far as I have heard player numbers have been growing, so here I am doing my share of spreading the word. This game is alive and kicking and pretty damn cool.
There is this guy Gyle who does a really good job commentating SupCom games and I find it pretty entertaining to watch. If you are in any way interested in multiplayer RTS's you should give it a glance, although the game specific terminology might dazzle you a bit. Here is a full game cast, these are top class players:
You only need to buy the Supreme Commander Forged Alliance standalone to be able to play the entire multiplayer, which is 10 euros on Steam. Then you need the Forged Alliance Forever client and you are good to go.
