The first gaming machine I every messed with was a TI99/4A computer. I remember playing several games on it including M.A.S.H which was a land the helicopter and then preform surgery by carefully tracing the bit of shrapnel out of a maze of a body. The Nintendo series followed shortly there after along with the Sega and Dreamcast with games like Road Rash, Sketichin, Mario Bros, Mario Kart, and Metroid. Now I focus on PC games that offer COOP play with a few versus here and there.
