Nice. We have a "native" Linux version now. It says, it requires Ubuntu, which is wrong. The Linux version runs on any GNU/Linux as long as it is on a x86-64 (or amd64) system. Rather it does not run on Ubuntu when Ubuntu was installed on ARM64 system.

So:
- Requirements in the GOG description are false
- We still need an ARM version of the game

A humble pirate.

ARM≠x86!

You're asking them to port a game to a completely different microprocessor architecture. Depending on the engine/underlying code, this can range from easy, to nigh impossible.
