The first video game I ever played as a kid was Space Invaders & Missile Command on one of the old Atari consoles. One of my old favourite games I played on the 3do was Space Hulk Vengeance Of The Blood Angels. Then came Xcom Enemy Unknown and Terror from the Deep on the Sony PlayStation. But my two really old favourite games have to be Wolfenstein 3D and D00M.
Downsampled to 3200x1800.
Great for old games and makes them look better.
