Oh, you shouldn't think about it too much! The fact that there are a lot of journey RPs or pokémon RPs as a whole now probably means that a lot of people like to play in those. They get filled up, I mean, right?
It's a nice thing that you're striving to become good, of course, but promise not to worry about that either :) In that case, I think you should focus on Reapers, because like I said, it really seems to be successful. If you apply that level of good GMing on Novia too, it'll probably be great as well!
