That is just not true. Ubisoft has had key rebinds for ages and they're not the only ones. I just wish I could know when a game doesn't offer that feature before buying the game. That is a critical info sellers just don't care giving.

Even though sometimes the dev themselves don't give the correct info, like you can rebind but not the default movement controls, like WASD. :/ It would have to be quickly tested bu GOG staff.

And know if a game will have quicksaves or just console like saves. They could have just let us add games with given features to GOG Mixes but they opposed that to the point of destroying the whole system. We cannot tag games either. You can presume by default nowadays that games won't have quicksaves and key rebinding and are made having the Switch in mind more than a PC.
