I spent all last night playing this and honestly it's fun. it has mmo elements, rpg elements, arpg elements, and maybe even idle elements. you can give every player attribute points(strength, vitality, etc), you level up their special skills(ss and above get three skills to use and below get 1 or 2), you get gear for each character and you can level that. you can group up with friends and randoms. there are dungeons and raids and pvp. there's probably more. if you like idleon you'll probably like this game.
