Ok, I have installed Wine, but it seems unable to install Avernum. Is this because it is only able to run Windows applications and not install them?
EDIT2: To answer my own question. I am a retard - I just had to right-click the .exe and choose Open with Wine, and then it installed just fine - I'll report back on the actual performance.
EDIT3: Running it in WINE turns out to be very slow, so I think I'll just play Avernum on my stationary only..
EDIT: Some system information:
I have switched a former windows machine to Ubuntu to increase performance - I am currently in the "demo" version, so windows is still in there somewhere.
My harddisk has 27 GB (only 12 free), so space is very limited.
I would prefer to be completely windows free, but who wants to lose compatibility?
