IdleOn! - The Idle MMO

At first, you'll create characters for mining, smithing, and fighting monsters, but as you complete each World, MORE skills will unlock -- like fishing, alchemy, construction -- which all give bonuses across all your entire guild! And of course, you'll be specializing new characters into each of these new skills! Eventually, you'll be controlling dozens of characters, all with unique classes, equipment, and abilities that YOU chose! Each one will work while you're Offline too, so progression never stops!
