SM64DS has vastly less runners than the original SM64, there are more than enough categories already. If there was actually substantial interest from runners to try out some of these new categories then they could be created at that point, but creating categories and then seeing if people run them is a fairly backwards approach. As it stands, the one extra misc. category that was added recently (All Characters) doesn't even have a single run yet, which I think proves my point that an even wider selection of categories is not needed or wanted at the moment.

But if you don't add these categories how will people get free WRs without putting in any effort??
