How about a Submachine complete series speedrun after The Exit comes out? All 10 games completed back to back RTA style?

That's a wonderful idea! However, not many people do runs of Submachine 10 because it's so long. So no one would be on the leaderboard for that ever. If someone were to do a speedrun of all 10 games and send video evidence of it to us, we might make that a thing. Even then we'd have to make a bunch of rules about the run. It's just unlikely. Also it's not necessary to make that a thing.
