As per title I bought the game, then downloaded through steam and tried to launch.
On launching the games, nearly immediately a red Attila loading screen is visiualized, but then nothing seems to happen after that.
Even after waiting 20 minutes.

Operating system is Arch Linux which is kept up to date, mesa drivers (radeonsi) and radeon 580 8gb vram.
Despite the fact that Sega supports only nvidia vga on linux, the game should work because many people have the game running with the same drivers I'm using.
So I've never been able to launch the game. The launcher always stay on the initial loading screen.

Anybody encountered the same problem?
Normally games work fine on my system. I'm more inclined to think it's something to do with the settings (or missing settings) in the preferences file (which I tried to locate without any success)
or parameter with the launcher (which I never touched, but maybe some parameter is needed to successfully launch the game).
