Alex the Historian posted another review of the sim. This one is a bit more like a “walk through” so it’s almost an hour long!
At some point near the beginning he said that the sim gives a window into what the early days of Disneyland was like. You’re exactly right, Alex. That’s what the sim (currently) aims to do. Sure, the park may look sparse, and there are only two engines, but that’s what it was really like!
Enjoy the show!
