I imagine that the reason why this campaign is not included in the all campaigns category (and why it is in misc) is that it is very different from the rest of the campaigns and some potential runners who might might only enjoy the RTS part of the game, not the RPG. However, I agree with moving it out of the misc, and maybe adding a misc category "all campaigns + rexxar" if someone wants to run it.

Rules: I would add one more rule - the run must be done on a new in-game profile, and the creation of this profile must be shown in the video. This is because the saved sub-maps are tied to your profile, not your current playthrough, and I suspect there would be some exploits abusing this fact.
