If you enjoy playing online games, or have been wanting to give them a go, then you may be interested to know that Team Fortress 2 is now free to play!
Personally, I think it's a pretty good game, even if it has outgrown my PC somewhat, largely due to all the free updates it's received over the years. So why not give it a go?
Who knows, you may even end up fighting alongside one of your forum bodies (or bludgeoning them to death)!
