Games that push their hardware the hardest

Hmm...  No one have an answer to the question in my post?  I realize it's kind of hidden in a wall of text.

Here's the TL;DR version.

While recalling Zero Tolerance and looking for similar games, I started to wonder about the origins of the "console shooter" and whether there are even earlier examples.  ZT came out in 1994, the same year as Battle Frenzy and Super Noah's Ark 3D.

Now, I know there are examples of FPSs on console prior to 94, but as far as I can tell, these tended to be games that were ported to console after starting out on some kind of home computer system.  I'm looking specifically for FPSs that were developed for console.

Zero Tolerance and Battle Frenzy were both developed for the Mega Drive/Genesis, and Super Noah's Ark 3D was developed for the SNES (it was later ported to PC, but that's ok because it appears to have been designed initially as a console game).

So, was 1994 the year of the console FPS?  Or was there something earlier?
