With the upcoming port to Unity, I believe it a console port could help jumpstart the playerbase and bring in new players. As free games on the Microsoft Store and PSN Store always get downloaded and played by a lot of people.
If you’re thinking "It wouldn’t work because ROTMG wouldn’t be very playable on a controller: it would not matter. It would get played regress-less of how bad it controls and more importantly it would appear to more players and a larger player-base than it is currently just on PC. New players would see the game and play it and maybe if they do not like how it controls on console they may try it on PC.
You look at a game like PUBG with it’s terrible port when it first came out on Xbox One, it was still one of the most played games and still currently sits at the 8th most played Xbox game and that version is a shell of it’s PC counterpart. I am not saying ROTMG would pull in the same numbers, but it would bring new players.Unity already has the Multiport to develop anywhere from IOS to the 3DS, a console port could be essential to bringing in new players and powering this game back up.
