In my opinion, the best multiplayer game is called: Lightbike 2 (free game)
you have to pay for wow.... Try wolfteam an uber online multiplayer game made by softynx copied by modern warfare and counter strike! AND ITS FREE
Team Fortress 2 is a great free multiplayer co-op game.
You cannot get Minecraft multiplayer for free. You must buy the game to be able to log onto a server.
A game called Sudden Attack, made in Korea
There are many websites which have free online multiplayer games. For instance, Texas Hold'em and the game called Scrabble are multiplayer games and are available to play through websites such as Pop Cap. Game Sheep and Free Arcade also have multiplayer games.
minecraft is the best answer you can play free at minecraft.net you can also buy the game and get more from it but other then that minecraft is the best answer all the rest like manic digger are just copy's of minecraft and are not that good minecraft is the best one minecraft is online multiplayer its even multiplayer on free version
runescape, dude.. doesnt have 3d graphics but other than that best game ever :D
yes it is free, and fun make a profile first on main menu click Multiplayer then go to internet (u need connection to the internet) making a game is more difficult then click refresh then join a game with free space e.g. 16/16 is full , 12/16 is not ! usually the game at the top of the list will run the best ( less ping) and then have fun !
yes and is a great game to paly
gunmaster onslaught 2 or if your looking for a free game online, try Combat Arms from Nexon, its pretty fun
battlefield:bad company 2 is the best game of 2010 and the best multiplayer game
