You’ve likely listened to the same or similar lectures I have on level design and I seriously apply those lessons to every single game and UI I have influence over!
While some might not consider it a game mechanic I certainly do, as gaming the proceduraly created levels is a core part of certain games, see mapping tactics in Diablo 2 for example as you use knowledge of procedural generation to reduce the time to find and kill bosses!
I haven’t found a mod that handles what I expect from building an empire, and it would require a decent bit of work, which I’m not currently interested in doing myself.
Nintendo had a stake in the company doing the broadcasts but is extremely unlikely to have retained copies of the levels.
The only way to have retained the levels is by having received them by satellaview and then disconnecting the device, for 25 years, and hoping the memory isn’t too volatile to recover.
It’s extremely fortunate that some people recorded levels on VHs and that those VHS weren’t damaged or lost.
