I loved TIM, was actually looking for it, but could not find it, was also looking for a modern incarnation of it, but haven't had any luck there either.
I do not really play any on-line games, RSA service a bit sucky for that.
I also agree with HiTech on COD4, that was great, have finished it something like four times already.
I enjoy BF2 and CS from time to time, just to get the brain away from things, it's not to involving, and after a couple of maps played you can stop playing without wondering what's next.
I am also completely crazy about NFS: Carbon, have played that through about five times.
You might say "Are you not to old for such computer games?" I should probably answer yes, but HELL NO!!!
