Rift is a fantasy MMORPG that's similar with World of Warcraft. The game is played on huge maps which generate rifts from time to time, forcing the players to close them by joining their forces. The game is truly a free-to-play MMO; you won't have to spend a dime to access all its zones.

Guild Wars 2
Look, I know that this game has some limitations. I mean, it offers free access to lots of zones, but you'll have to pay some money to get access to all its features.

League of Legends
League of Legends' developers have used Dota as a source of inspiration - there's no doubt about it in my mind!

Add to this the huge number of player characters with unique designs and play styles, and you'll understand why LoL has over 100 million fans.
Team Fortress 2
If you want to play a shooter game that's truly free-to-play and 100% fun, Team Fortress 2 is a terrific option. The game is constantly updated, even though I'll be honest with you and admit that its graphics look a bit outdated. Nevertheless, TF2 continues to offer a very rewarding gaming experience.
