The Good
This was one of the first text adventure games I ever played (thus, why I never beat it, I suppose) but I remember there was a lot of 'action' packed into it -- the npc's wandered about, there was a lot to explore, and you could do some really neat detective command like ANALYZE '[crime scene object]' or 'ARREST [suspect]'. The game also came with some really cool documentation with a coroner's report and a bunch of background info.

The Bad
It was really hard.

The Bottom Line
If you're into text adventures, or Infocom, this game is definitely worth a look. Also, I don't think there's a difference between the booter and the dos version, but I may be wrong.
