Basically erm, the game isn't designed as a Linux game per se but does run through Wine and this is covered by the official website. It used to be pay-to-play but is not free-to-play and the reason I am posting about it is that the game has recently moved over from the company (which went out of business) to the community, who now run it.
The game is struggling a bit though, and I'm sure they wouldn't say no to some really great coders to improve it!
You have probably heard of it, it's now TEN YEARS OLD!
Let me know what you think!
