Rollercoaster Tycoon 2
I bought Rollercoaster Tycoon 2 on GOG.com recently and it’s a great nostalgia trip. The best thing about buying it from GOG is that it works great on Windows 7, I haven’t had a problem so far with compatibility.
Even the original disc version I had on Windows XP didn’t seem to work as well. I recommend this site if your looking at buying some old games again. If you’re going to get Rollercoaster Tycoon, get the 2nd game as it has loads more items to play around with and you can import all the 1st game’s maps to use.
