built a reasonable clone in ~48 hours

… This seemed hard, because RCT2 requires a lot of understanding of geometric space, a lot of art assets and animations, and a lot of complex interaction patterns. The agents built a reasonable clone in ~48 hours, with just a claude max and codex max subscription. I spent the next week playing it, because I love coaster sims, and tweaked more of the gameplay elements that the agents missed.
