Have some time to waste? I know I sure do.
I played every Wing Commander game back in the day and loved every single one (Prophecy was a bit meh, but passable) and didn't even know this existed, but fans of the series have taken the FreeSpace Open Source engine/code and made a Wing Commander game with it. It's actually pretty damn polished and the voice over work isn't bad. It's better than most eastern European game voice overs (though that isn't difficult).
The timeline is set within the Terran-Kilrathi War, so you'll be killing the space kitties rather than fighting with them. Like the good old days.
