looking for a good, free online game

Im looking for a game with decent graphics, free to play, with a good class system, mounts and jobs. Any suggestions?

Your best bet is probably Lord of the Rings Online.

Agreed or the Guild Wars series if you have not had the chance to enjoy them yet. I believe that you have to buy the game client though. Might not be waht you are looking for.

Vindictus, but it doesn't have mounts, not really an open world, but it's free! I think it has a few classes, a bit fun too. (100% free, don't have to buy it)
