3/4 Isometric on the 2600

I've said it before and I'll say it again.  Just who got the bright idea to put games on the Atari 2600 that use a three-quarter isometric perspective?

Experience has taught us that the 2600 CANNOT  handle isometric perspective.

Examples:

Congo Bongo

Desert Falcon

Up 'n Down

(All these images BTW are courtesy of the Atari Protos page.)  Anyway...YECCH!  Didn't programmers understand that these games were proof of the 2600's poor handling of isometrics?
