Games, both online and on mobile devices, draw such an intense following that often there are fan communities and forums created entirely around a single game. PlayHaven is hoping to empower developers with the tools to create their own online and in-game (for the iPhone only for now) fan communities for free.

PlayHaven has created shell communities around 15,000 games on Apple’s app store, so most developers can automatically claim their community. If their community hasn’t been pre-created, developers can also create their own communities. The transition between online communities and in-game communities are fairly seamless, says Raymond Lau, co-founder and CEO of PlayHaven.

Lau says that in-game communities on iPhone apps can be integrated by inserting a snippet of code. In the app, the “community” feature will be able to be accessed under the menu button, so users can access the community from within the feature. On both the app and online communities, fans and developers can share their passion for games by creating guides, tips, reviews, and other content. Developers can also have a channel to connect to fans to notify users of news and new releases.

PlayHaven is already testing its communities in-game and online for several apps, including Geared, Minigore and The Quest. In fact, one-third of all Geared players are active on PlayHaven’s community on a daily basis.

Competitors include OpenFeint and Plus+.
