Some of the hurdles to developing the games on Linux have to do with the diversity of the particular Linux setups and how many would need to be supported.
We've investigated bringing the games in this collection to Linux. The costs involved in development, continued support, and based on the size of the potential audience, the idea is prohibitively expensive.
We know there’s a dedicated group of people who want the games on Linux, but it’s not anywhere big enough an audience to pay the bill for this.
This doesn’t mean in the future we can’t revisit it, but for this project, Linux development is beyond the scope for this collection at this time.
Never say never.
