As the event progresses, each month a theme will be given. This theme may be expanded upon a little bit but in most cases would remain vague as the fine print suggests.
Say theme for the month is some sort of multiplayer replay - where collaboration has been disallowed. As in, we aren't expecting a sparring replay. So we'd probably love those juicy decaps on aikido, or some sick skeets on BOXSHU (again, these are just basic exemplifications, we're looking for anything really). In this instance, you're not allowed to collaborate with the other player to make the replay more impressive than you'd be able to make alone.
