actually andrew, it was the first side crolling adventure game for PC.
Actually,
Captain Comic was the first Mario-style side-scroller on the PC that I know of, although there might have been something more obscure. I loved that game back in the day and used to beg my dad to let me play it on his PC at work in the late 1980s.
also was the first solo project of the 3 co-founders of iD software. theres a whole story behind it and i would gladly take over writing it, RW you reading? lol
In 1990, DOS PC gaming made a breakthrough in the genre. Commander Keen, released by id Software, became the first IBM-compatible PC platformer to feature smooth scrolling graphics thanks to a technique programmer John Carmack had pioneered for EGA graphics displays.
I know these things, but there are only so many hours in the day and a million things I could write about. Please feel free to write an article about Commander Keen and send it to me. I can use it as the latest in the "Great Moments in Shareware" series.
