A great evil has come across the land and it's up to you to destroy this horrible evil. That's the the premade single player game. Shattered Light comes with a World Builder that lets you create maps, write quests, create weapons, write NPC dialogue, and much more.Then when your world is full of quests and evil monsters to slay you can take it online with eight other people and, if your the host, modify player attributes on the fly. Not too many games let you host worlds you've made and then change stuff in the middle of all the action.
