Fun and free multiplayer online games?
 

Well I was looking into maybe start playing some free online multiplayer game again, not MMORPGs but free online games like Albatross 18, Gunbound and so on. Is there anything new or old that I may have missed that despite being free are damn fun to play?

Haha, I'm so stupid, I hadn't noticed the "Multiplayer Arena" forum yet, well now I have and this thread is useless as my answer is probably in there.

I highly recommend Soldat or Clonk. Soldat plays like a 2D version of Unreal Tournament while Clonk is a brilliant presentation of how RTS can work in 2D. If your more into space simulation games like Privateer or Freelancer, then I would highly recommend the Evochron series. Though Evochron plays mostly offline, you can bring your character online. The game Gunz Online is pretty good as well.

Play and see them for yourself, I would say.
