Just a new misc. category for Legacy Levels would be cool.

Not sure what you mean by Legacy Levels, but if it is basically like All Stars - NNS but just Legacy worlds, then I'm not entirely sure it warrants it's own category. The run would be just around 3 minutes, and it would be the exact same as the last part of AS-NNS. That being said, if you or anyone else actually does a run I might re-consider it. For now though I don't see any good reason to put up a new category. (If I misunderstood what you meant the category should be, then obviously elaborate on what you actually meant and I'll consider things based on that)
