Back in 2000, I was working at a startup, and one of our rabbit trails was an IF interpreter for z-machine games on mobile phones. At that time, you could count on about 4 to 6 lines of text to be visible on a phone at any one time, and text input was horrendously tedious. Our founder approached Andrew Plotkin about licensing his games, and he was reportedly "kind of a dick" about it. Considering the source, that might have been projection.

I shudder to think of what might have happened if that company actually turned a profit from something, and this thing in particular.
