furrykef: Not at all true. The DOS version is much buggier. There's a big ol' strategy guide from back in the day that kept pointing out bugs in the simulation and other parts of the program, and I'm pretty sure the DOS version had more bugs than the others. I also think the Windows version had better music selection. For instance, the Windows version picked a track (a very good choice) to be the game's theme song, and you heard that every time you started the game. The DOS version seems to pick a track at random when you start the game, and the result is awful. It might lead off with the most dark and dreary tune in the game, and that's not a good mood-setter.
Atlantico: Right. So since it is "not at all true", perhaps you'd be so kind as to list all the salient changes - but of course if nonspecific bugs and a debatable music change is the lot of it, then perhaps you'd want to look up what "not at all true" means.
Let's see: the Windows in Sims City 2000 SE for Win95 are actual Windows and can be dragged around with no problem. This feels less clunky than the DOS version.
The main window can span the entire width of your monitor is you're using a wide screen monitor. That means more of the map can be seen at once, that makes managing the city easier.
More building choices with the SCURK plus the ability to make your own.
Better animations on just about everything.
An extra fast speed mode that the DOS version never had.
A better Disaster drop down menu with new Disasters.
Speaking of drop down menu's there's a key combo that unlocks the sandbox drop down menu in the Windows edition. No such menu exists in the DOS version. This mode lets you play SC2K as a Sandbox game although you will still have to manage budget and sim happiness.
Easier to use terrain editing tools before starting a new city.
I may have missed a few things but those are the ones I can think of off the top of my head.
Oh and if you have SimCopter and Streets of SimCity SC2K SE for Windows lets you use the maps you make in the game (or SCURK) as maps in those two games. But since those two games are not here on GoG that's kind of a non-starter.
