Contrllr will be a community very similar to how Letterboxd have set their site up, but focused on games instead. There's plenty of gaming sites out there, where the final site is a mix of all things. Contrllr plans to be a site where you can review games, makes lists, share your game progress, import from XBL, PSN and Steam for achievements and game lists, and more.
