Freespace 1 would like a word with you. http://www.youtube.com/watch?v=NJ-xcgBL1mY
I feel terrible. I didn't even know that Freespace was related to Descent. Now I'm going to have to buy more games during this sale!
It is a great game but only sort of related to Descent by development
. That said you should still get it. :) For it is indeed awesome. Also for Freespace 2 there is a great open source project for its source engine which has kept the game looking and playing really well (and you can play Freespace 1 in that engine).
