We all know this is the best space sim ever made. What you might not know is that Volition open sourced Freespace 2 before closing their doors for good, spawning the Freespace Sourcecode Project. If you can extract the GOG installer on a Windows PC (or in WINE), you can use the FSP installer to install on OS X or Linux (or Windows) and give the FS2 updated graphics! Yea!
