I'm a big fan of Spiral Knights, but having gotten the Battle Pack and an Elevator Pass I'm close to acquiring a Divine Avenger, Polaris, Acheron, and Leviathan. Not attempting to get people to "advertise" or trying to be a jerk to OOO - SK will always be a priority for my gaming life - but I think I need to occasionally play something else while I get off my Spiral Knights addiction.
Just asking if people know any good MMO games like Spiral Knights - free to enjoy, no crappy monthly member subscriptions, creative artwork and gameplay, etc.
Vindictus (also known as magnobi heroes), its free and looks really fun, its an action MMO, and reminds me of moster hunter, but in dungeons.
