The emergence of the 3d platformer
3d platformers, and games with 3d platform gameplay, are super common today. This thread is the about the early evolution of the genre's elements prior to what I would consider its modern form: 1996 releases like Super Mario 64, Crash Bandicoot, and Tomb Raider.

Heading back to 1983, some of the elements of 3d platformers had emerged. Atari's arcade game I, Robot was ahead of its time with its shaded polygon graphics. While not truly a platformer, your character did have the ability to make automated jumps when pushing the joystick to edges (like the auto-jumps in the 3d Zelda games years later).

Also from '83 was Spike for the Vectrex. Its gameplay was completely 2d but its perspective foreshadowed many "2.5d" games of the mid '90s so I figured I would mention it.

Another game which wasn't really a platformer but I think is worth noting is Square's 3-D WorldRunner for the NES in 1987.

It wasn't polygonal nor can you jump on platforms but the "Space Harrier on the ground" gameplay bares resemblance to linear, on-rails 3d platformers like Crash Bandicoot, and appeared in other pre-1996 games like Jimmu Densho Yaksa (1989) for the PC Engine as well as bonus rounds in 16-bit Sonic games.

As far as I can tell, the first true 3d platformer appeared in 1990, Infogrames' Alpha Waves (AKA Continuum) for the Atari ST. It was ported to Amiga and PC. Alpha Waves was a breakthrough title; it was polygonal and allowed the player to move around and jump in 3d space.

Despite an increase in 3d polygon games in the early '90s (moreso on computers and arcades than on consoles and portables), most of these remained in the racing, FPS, simulation, and shooter genres. First-person shooters later incorporated platform gameplay but early ones usually lacked the jumping aspect.
In 1994, Exact's Geograph Seal was released for the X68000 in Japan.

It's the direct ancestor of 1995's Jumping Flash! on the Playstation. Gameplay in these games consisted of first-person platform jumping and shooting.

Realtime Associates' 1995 Saturn game Bug! deserves a mention, too. It didn't have free-roaming 3d but it did allow for vertical movement in a polygon environment, and unlike the hybrid gameplay of Exact's games, it was purely a platform game.

Did I miss anything noteworthy from before 1996? It seems like there should be more.
What are your thoughts on the evolution of early 3d platformers and its predecessors?
