I've seen related topic and posts in the forum. -but because of being closed to new posts, I have opened that.- The game may be designed for windows, I respect that but there should be an option for linux users, too. People don't have to choose windows as an OS. People are free to choose their own OS. On the other hand, exe-formatted plugin just copies needed files to system path. It can be converted both compressed form or DEB-like package system form. Linux users should NOT BE RESTRICTED from this game, I think.
You have a very good point here, and although I don't know a great deal on the whole Linux built OS, I'm sure that in time the game will be converted into Linux form, so that more people are able to play the game. However, it's not a surprise that there is not a Linux version of the game, because it's not very common in comparison to the Windows OS, or the Mac.
