Also on Steam is the Jedi Knight Collection for $19.99, it includes the original Dark Forces, Dark Forces II, Jedi Academy, Jedi Outcast and Mysteries of the Sith - Looks like I'll be buying yet another throw away credit card. No word yet on compatibility issues like those that arose in the original Red Factions that were released, but hopefully it will be smooth sailing.
Edit: It seems that the early games like Dark Forces II and Mysteries of the Sith (both games I haven't played) suffer from various game stopping bugs and issues. Still a good deal for what works but buyer beware.
