This is a 1 shot result from the following prompt with Claude 5 Opus:

hi id like u to create a 3d environment for a possible future game. the player is inside a roller coaster wagon. but the wagon is inside an haunted ride attraction. the ride itself essentially goes in a circle, so the player keeps seeing the same props the player can look around with the mouse, and choose to go faster or slower with W and A. when he looks around, it's dark, but some stuff have lightning on it (of various colors) and we can see various hallowen props or other things you would find in such a haunted ride attraction. U could even try adding some small stuff like a prop popping out as a surprise etc. You can include the appropriate sounds to go with this. make it polished and do ur own assets.

I wanted to see if Claude could reproduce those sort of haunted rides. And what i find interesting is it would be relatively easy to turn into a game where stuff randomly pops and you shoot it.

I did not give it any assets, or give it access to anything. It used Three.JS
The player can look around with the mouse and he can also speed up the ride.
