First of all, my thanks to Magnus Olsson for the z-code port of this game. So much easier to load up Filfre to play this rather than trying to get an ancient executable to work or what not.
I had never played this game until today, but had read about it many times. For the time in which it was created I'm sure it was a fun little game. Even in the modern era I enjoyed playing it for a bit and I'm sure I will introduce it to my kids one day as both a logic problem and computer history lesson. That said, it is just a puzzle/mapping game, no real story to it.
I recommend everyone play it for an hour or so to appreciate where IF started and where it is today. Still fun, if only for a bit.
