Can't think of any other game to put on this list.
1. Cod 4 MW
This game introduced me to and can't put a price on that. Before this game , i didnt even know we could play games with other people over the internet.
2. Rocket league
I mean who even of thought of this game, playing soccer with cars xD. Its the only game i have been playing now a days.
3. Gta Sanandreas
Besides all the memes, Had a lot of fun playing multiplayer.

Such a unique game. The gameplay, art style is different from other fps games. Sad to see, bad servers and bug
