Maybe you can find some old stadia controllers for cheap and convert them to Bluetooth controllers.

Edit: looks like most of the used stadia controllers I find are close to $20-30.

Access software made several games for the C64 that had multiple perspectives.

Beach head and Raid Over Moscow both had multiple stages that were each really separate mini games.

And does crash bandicoot count with the switch from trailing camera to side camera for the ? Levels and the reverse direction leading camera for the crash bash levels?

I believe EA was made permanent winner back in the 00s, and barred from competing after they won 8 years in a row.
