If you do launch on Steam, please DO NOT try and force users to move to the Steam version - maintain support here.
The Steam client has been known to be causing medical issues for some users since late 2019 and Valve have openly refused to address any of the problems (there's multiple problems with the update which are triggering issues for different people). In June last year they made the problem worse by blocking access to the only safe workaround that existed when they first caused the problem.
