The version I played is, I'm pretty sure, a shareware version (ver. 5.1) from 1985 (by Don Phillip Gibson, if for some reason you feel like searching for this and you can even find it somewhere). It doesn't have an option to play against the PC, so you can only play with 2-4 human players. I played against myself and played as I normally would until there was a winner.
It does the job, holds to all the rules, so it's a viable option if there are some people that want to sit down and play a game of Monopoly without setting up a board. Only supporting the PC Speaker does make what little sound effects there are pretty annoying, especially since there is a really annoying sound for the dice "rolling" until you press a button to make them "land". You can toggle the sound on/off, so you can make that annoyance go away. It's pretty minimal graphically, which isn't surprising since, according to the document file that it comes with, this was used by the programmer to teach himself Turbo Pascal. It would be nice to have a simple Quit Game command, though. While it's not necessary, I did run it through DOSBox just to be able to see the movement of the game pieces (and it also has the added benefit of making the dice rolling sound a LOT less annoying).
