I am thinking about getting into speed running soon and i was wondering if there was or could possibly be a category for Expert Sphere Grid runs.

Sounds pretty mundane as its own category. As far as I know, there is no rule banning ESG in the remaster categories. Why not just use that in your runs regardless of other runners strats?

esg would just be any% probably. tho never hurts to ask in the discord or message cereth if you really want a answer.

It has existed in the past, but I believe only had one run (by Flobberworm4), and it wasn't very well optimised. It can be added again if you're able to show some passion and seriousness toward the category so it doesn't simply rot away as a poor excuse for a leaderboard again ;)

Just trying to avoid situations where people do one or two runs and then nothing ever comes of it. A leaderboard needs competition to really serve any purpose.
