Dawn of Worlds is a Tabletop Game that is distributed for free. Find it here. Unlike most role playing games, in which the players roleplay as mortals on quests inside a world, Dawn of Worlds has the players roleplay as gods making an entirely new world--a collaborative world-building exercise.
Gameplay is divided into three phases: the First Age, wherein the gods shape the world, creating forests, mountains, rivers, deserts, swamps, etc., the Second Age, wherein the world is populated by races, and the Third Age, wherein the various races of the world interact with each other. Note that each Age is not exclusively about one aspect of the game; a mountain can be raised in the Third Age, but it will cost more power to do so. Power is determined each turn by rolling a 2d6, and players receive power bonuses by finishing a turn with five power or less.
- Always Chaotic Evil: Spend enough points corrupting a race and you get this.
- Character Alignment: The players may decide to style themselves as Dungeons and Dragons-type gods, in which case they usually take up a particular alignment.
- Did Not Do the Research: Unless any of the players are particularly anal geologists, nonsensical climates and geographies are going to pop up.
- God Is Evil: If you want to play an evil god, go ahead.
- Incorruptible Pure Pureness: Or this.
- Loads and Loads of Races: It takes six points to make a race in the second age. You can save 10 points by circumventing the 22-point race cost in the first age by spending 10 points on an avatar and 2 points to command your avatar to make a race. The world inevitably gets crowded.
- Ninja Pirate Zombie Robot: If you want to make one, you can have it.
