As I understand it, even the most current version of the game links to a horribly outdated version of openssl that is no longer shipped by modern Linux distributions. The publisher has neither fixed this nor bundled the version they need, so you will not be able to start the program due to missing openssl-1.0.so. Most distributions provide a special package to install this legacy library, commonly named openssl-compat or similar. You could also choose any of a number of highly questionable sites that purport to host downloads of this obsolete library.

Meanwhile, Wine runs the Windows version of the game fine. If I recall correctly, I didn't even need to adjust any settings in Wine to get it to work.
