I used to play the windows version of this when I ran Windows XP. I had a 1600x1200 monitor and I could fit SO MUCH of my city on my screen. This dos version runs at 640x480 and the music is AWFUL. There's probably a windows version floating around somewhere that has been modified to work on a 64-bit operating system, I know they did it with Sim Tower and a few others. My opinion - the fact that it's a dos version is a deal breaker. Don't buy.
