We are only two on console. I don't think is relevant to split the leaderboard with empty category (because lot of console, PS4/5, Xbox one/series, switch).

Maybe a glitchless category is more interesting ?

As someone who is looking into the run and only owns the game on console I think splitting the boards to PC and Console could be beneficial. Specifically because of how much time PC saves on loading, I don't think many people who get into the game on console would see the possibility for having higher ranking times or general competition with PC players. Just something I figure could be thought about again with the upcoming release of Mirage potentially bringing eyes back on the Assassin's Creed series as a whole.
