Steam has a nice catalog of games that you can view at the URL below. Some of these games have different pricing models, they are free-to-play, but many follow a "freemium" model, where players that pay cash get the best experience, and many of these models can easily become more expensive than a normal $50-60 game if you don't watch yourself.

You can view that entire catalog here: http://store.steampowered.com/genre/Free%20to%20Pl...

Other notables:

RuneScape <runescape.com> - The game has evolved for over a decade, and is still one of the most popular free to play MMOs out there. It can be addicting for achievement junkies, but the game itself is generally a grinding game.

Dota 2 (through Steam) - I did send you to the Steam site, but I believe Dota 2 isn't *technically* on that page I sent you to. Dota 2 is the sequel to the Warcraft 3 mod Defense of the Ancients, and is a Real Time Strategy game. The game is in beta, but Valve sent out so many beta keys that they are all over the internet, you can ask almost anyone who plays and they can supply you with one.

League of Legends <leagueoflegends.com> - This game is a RTS that follows in the footsteps of Defense of the Ancients as well, but it is still different. The game from my experience is a more "hardcore" experience, and those who master its ins and outs are going to have a blast. It is completely free to play, the catch is that you get about 10 playable characters (known as champions) to use every week, and you can buy them permanently after each week if you really love them.

www.mmohut.com has a great list of free to play games.

Other great ones I love are league of legends, warframe, planetside2, APB Reloaded, Team Fortress 2, and DC Universe.

Get League of Legends. Best game ever. Most played game ever as well.
