This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
Just post some stuff and don't spam.

I was so shocked first! Back when I was a kid I was super hyped when a Hungarian team had announced that they would make a Doom knockoff called Boom! I bought the game as soon as I could, and while I still played it a good bunch, I was a bit disappointed that it was basically an old RPG style 90-degree-turns-only, central projection kind of shooter with mostly static (non-moving) sprites and joystick aiming. And that was pretty much all that they could squeeze out of the hardware, spread over several floppy disks.
Since the map was mesh/cell based, and every enemy was in the center of one cell, it was faster to just turn-move-turn-move-turn and shoot with a centered crosshair than aiming with your constant speed joystick.
Even THAT game had serious frame rate limitations, so I couldn't believe my eyes when I saw the gif.
If you're looking for an honest-to-goodness running on C64 hardware FPS experience that is as close to Wolfenstein 3D/Doom that we've seen so far, there is a really impressive demo from jimi9757 where he made a ray casting engine for c64. You can see that here.
Perhaps even more impressive is he made a version for the Commodore PET too.
Holy mackerel, this is cool! Thanks! I also played Total Eclipse, which was a bit closer to being 3D (and Stunt Car Racer!), but this jimo stuff seems to run much faster.
