i would strongly recommend Lord of the Rings online, its a great MMORPG! on second place try Atlantica Online, really fun game too, and free and yea League of Legends ofc, a great game also. you can also try CABAL Online (havent play it but few friends told me its worth trying), Runes of Magic like darthdave9 said, Mythos (i only played beta and was kinda nice but not my style), Dekaron, Requiem: Bloodymare (horror type), MU Online (pretty old but cool), and Battle of the Immortals ( a little more grinding then necessary) of course if you dont like any of these games you can always go to www.mmorpg.com, click Game list, click sort by Rating/Hype and pick one on your own (it says which ones are free too) i hope this helps
Try Fantasy Online on konegrete.Its a great game! Its one of those pixel favorites. Or just go to google and search any mmorpg you want. I hope i helped.
Age of Empires is a cool MMORTS that's free, and if you shell out 20 dollars you can get a premium Civilization. Its a lot of fun, the art style is awesome, and the premium Civs are worth 20 dollars, but the whole free experience is worth it by itself.
Lord of the Rings: Online (or just LOTRO) - if you don't want to pay $15+ a month, then I don't advise this game. The "free to play" is very limited.
My advises: 1. Atlantica Online - a great tactical game, but quite hard to play without Item Mall at high lvls. 2. LoL - an awesome game where you can manage just fine without paying
Go to MMOHUT for a lot of free MMO games. Ok, so these are the games I tried and recommend: Perfect World: The best character creation system in MMO RPG Combat Arms: Fun game! Don't have cod? then play Combat arms! Dragon Nest: When you like skilled games not like a targeting system game I will recommend you this! Cross Fire: The installation is only about 240MB. The HERO MODE is the best!!! Grand Fantasia: A game that you might get addictive in with PvP! Now with a mount for 2 players and a PvP server. Dungeons & Dragon Online: Fast paced game. The character creation screen tells you a lot of the characters.
I could recommend Lord of the Rings Online if you're into fantasy, and Champions Online is another free MMORPG where you get to play a superhero in modern times, and it's got what is IMO the best character customization in any MMORPG (and I've tried Perfect World).
League of Legends is a good game too, as someone mentioned before, but it is not a MMORPG.
