SimCity 2000 is one of my favourites of all time. I bought it again during the GOG sale. Maybe we should post cities here. I haven't really "finished" any of the cities I'm working on now though, and smurf knows where the cities I made when I was younger are.
It really sucks that they screwed up the new one so badly; it looked like it had serious potential from the previews, but EA apparently forced them to rush it out way before it was ready and I doubt it'll ever recover. Plus that DRM was a horrible idea.
