Assassins Creed Brotherhood online is great fun. I use Xbox Live. Lucky for me someone paid for my subscription. The thing should be free not £5.99/month!
My favourite online game has to be starcraft 2, it is a RTS MMO. The game is very well balanced and I really enjoy playing it. I am actually part of a online coaching community where we coach players for free.
Online Games - Helpingme To Be Entertained And Relaxed At The Same Time .These games have become one of the best ways to relief stress after a busy day.my favorate online games are pool and car racing....
Dead Frontier is a good game if anyone hasn't tried it, its a MMO zombie survival game which is ran from the browser (no download needed) and is very well thought out!
Starcraft 2 in 4v4 mode is hectic and fun. As for online Flash games, I enjoy Desktop Tower Defense and most good TD games.
I spend much time on playing a putting game online here boomgolf.com.au/online-game if you have spare time, certainly you will need some resources for playing.
