You have to set the game platforms as selectable, they are: PS5, PC and Xbox Series X and S
I mean isn't technically necessary you can submit it just fine with no platform for it. Its a long run anyways so i doubt anyone will attempt a run on console anyways.
It is not unnecessary because you could put more categories such as making all the watchtowers, passing the prologue, act 1, 2, 3 and the epilogue separately and for this it is necessary to put their respective eligible platforms
Besides, it would be the first Assassin's Creed not to have them and it would be detrimental to the speedrun series and the runners.
For any of those non full game category to be added 3 active runners need to run any suggested category more than once then submitted to the forums. This game is super king and very little interest to begin with I would love those but getting 3 people to run for example act 1 is kinda hard
Listen unless people from other platforms actually run it for now it’s not a problem. I do think we need shorter categories for this game. I would gladly do a run just involving the prologue of the game plus act 1 as that’s a reasonable length. But we need 3 people to do a run and make multiple attempts so until said thing happens platforms isn’t a big deal
