Yeah I probably should save some keystrokes but I'll repeat it again here:
We are not ready for the influx of new players, on a forum/lobby moderation standpoint.
We are not ready for the influx of new players with the current mod situation
Regarding licensing we can't link with the steam api directly we would need to make a launcher.
We haven't looked yet into the specific of submitting a cross platform game.
We need to take what happened other games that did https://ftp.fau.de/fosdem/2020/K.3.201/gamedev_spring_steam.mp4 into account
Regarding auto updates, the game is now on the Windows Store https://apps.microsoft.com/detail/9n5vvjr2dz9w?hl=fr-FR&gl=US which i believe supports it.
I've merged this conversation with the other one.
There were similar threads in the past.
I think the summary is that the game is still not ready to attract a much wider player base, from a MP standpoint.
There is also a matter of integration with the Steam libraries, which the developers might not want to do.
