Hey John, thanks for Doom and Quake. I had lots of fun, and you and Abrash introduced me to 3D rendering techniques and advanced assembly programming techniques for which I am grateful since those skills put a little bread on the table long, long ago.

Would you ever team up with Romero to make another game? I'd love to see your guys' take on a battle royale game. I'm having lots of fun with PUBG, but a game like that needs your engine optimization-fu.
