So I just tried with the version 20.2.x from experimental. Things are even worse : the game crashes at once after login credentials have been entered (segfault). I do not get the welcome screen where you can choose which one of your character you want to play.
With sid version and other versions since 20.0.7-1 I get at least the (deteriorated) welcome screen. Sadly the error log generated from the game is only useable by the game devs... Regards, VB
