I bought Darwinia on Steam before I knew there was a Linux version. Is there any way to run it in Linux?
Yes. Thanks to Darwinia not using Steam for anything but content delivery, it is possible to run a copy of Darwinia from Steam on Linux. First you have to locate the content directory on Windows. This will probably be C:\Program Files\Valve\Steam\SteamApps\[account name]\Darwinia\. Then you need to download and run the Linux Darwinia installer from http://www.darwinia.co.uk/support/linux.html. Be sure to not have “copy CD data” selected in the installer. Once the binaries have been installed, copy the “.dat” files from your Steam content directory into the lib/ subdirectory of your Darwinia directory. You should now be able to launch Darwinia. Note: Introversion Software will not support Linux users who run Darwinia from Steam in this way, due to potential compatibility issues.
