We're excited about the upcoming Hand of Odd, which is sponsored by Hasbro and as such will contain many little nods in the direction of their most popular line of merchandise (such as posters advertising MLP, an in-game player to watch MLP episodes on, an MLP-themed interface and a "Pony Rider" unit for the Mudokon team).
