Hi, installing the "mono" package on my system helped to start the game (even with the Kick file). But unfortunately it's still not really running.
I can create a character now but when I start the game I only get a black screen. Also when changing anything in the configuration leads to a black screen even before the character generation/selection.
I tried some different start options (different LD_PRELOAD paths, start Kick, start Mystica.bin.x86, ...x86_64, Mystica.exe with or without mono) but nothing helped (but I was able to always reach the menu and get into the "black" game - sounds and music were fine and I was hearing sword sounds and so on).
So installing mono definitely helped, but not enough. ;-) Maybe you have another idea? Which mono version are you using? I have mono 6.4.0 on my system.
Thanks anyway for your quick answer!
