Just in case anyone was interested, I figured I would share this here-

GOG.com is running a 70% off sale all the classic X-Wing, Tie Fighter, and Battlegrounds games. $1.79 each.

I went ahead and picked them up since the only ones I ever played growing up were X-Wing and Rogue Squadron, and I hear people talk about how great tie fighter was frequently. Sale is limited time though, only 7h 30m left from the time of this post.
