The official World of Warcraft and official Minecraft wikis are hosted there, so it would be a good way to help advertise the game. In addition, by being hosted at Gamepedia, you would be able to take advantage of Gamepedia wiki services, which includes customizing the look of the wiki as well as being able to handle any wiki-related issues you may come across.
