I have just stumbled upon this site and I have a query about the various downloads. I have just purchased RCT Classic and I am wondering; would tracks and scenarios designed for the first two games work in Classic? I'm assuming that most RCT2 tracks would work but I imagine that RCT1 ones might be a bit trickier.

Tracks and scenarios built in RCT2 work in RCTC as long as they don't use hacks that RCTC doesn't support.

As far as RCT1 content goes, I haven't found a definitive answer either way, but I'm guessing it can't just be imported into the game the way RCT2 content can. There could potentially be a way to get the tracks in there if they don't use any elements specific to RCT1, but someone who actually owns the game would have to confirm this.
