Yesterday, on the 25th anniversary of the first Commander Keen release, id Software co-founder John Romero revealed a video of the studio’s Super Mario Bros. 3 demo. Created in a single week back in 1990, the year of Commander Keen, the demo was presented to Nintendo to show the viability of a PC port of the game. The second level has been redesigned to ask the important question: “Like it?”
Whether or not Nintendo did like the demo, history doesn’t make clear. What we do know is that they were concentrating all of their energies on games for their own hardware. How different the PC landscape might be if that hadn’t been the case.
