Better graphics than Runescape (its 2-d, but the graphics are pretty awesome[its a platormoer])
you don't just make one job choice. At first you start as a beginner, and get the feel for the game before choosing. At lvl 10 (8 for magician) you can become a rogue, warrior, bowman, or magician. At level 30, you then get 2-3 options for your second job(for example, a magician can become a cleric, an ice/lightning wizard, or a fire/poison wizard)
Free unless you purchase option Nexon cash used for making your character more personalized
Depending on which server you choose, you can be in a jam-packed world, or in a quiet world where you won't be bothered and have to fight for space to train.
Runs off a client, far fewer hackers than browser games, and the mods hold events/holidays often, which are tons of fun
Not true. On mmorpg.com voters have given this game an 8.0, the highest ranked game is ranked 8.4 by user votes, which is .2 points higher then the shoot load of games tied with 2nd with 8.2. And I personaly have played it, and it's not as good as other mmos i've played.
btw the editors of the site rated WoW 8.1 and the highest one that was 8.4 an 8.5 and there are 860,786 members on the site (stats taken right before post). But its the best mmo rating and reviewing place out there (to my knowledge).
The best free MMORPG I know is "The Kingdom of Loathing." It is a hilarious point and click turn-based MMORPG. I have been playing for 4 years under the same screen name.
