UNRELEASED PROTOTYPE: Robocop Vs. The Terminator for the NES - Playthrough / Gameplay Sample

When I was younger, I always wondered why 100% completed games never got released. Then I started playing them and I quickly realized why. About 90% of these cancelled games are just awful.

Robocop Versus Terminator is one of my favorite games on the Genesis. But this NES port was an embarrassing mess. This prototype is 100% complete, but the game is terrible. The NES could do better graphics than this... I've seen ColecoVision and Atari 5200 games that look better than this. The platforming action is solid, but the boss fights are garbage. Dumb AI, poor hit detection and basically just futile gameplay in general. I gave up playing the first level, the game just isn't a good experience.
