KR requires buying an account for <$10 but one can give you access to multiple games if they have the same publisher, which is often Nexon.

Dungeo-- Yeah, it's the same shit.
No patch, no community. Not that I know of, at least.
The first thing you're asked to input upon logging in is your family name or whatever. Displayed before your character name so don't input random shit. Or do, not my business really.
3 control schemes: pure keyboard (shit for skill aiming), point and click movement, WASD movement with both main mouse buttons being used for skills.
Important special feature: you can't have white hair. game sux dropped
