Just remembered that seeing Doom for the first time is another obvious one. Man that game was incredible when it came out.
I remember my brother telling me about Wolfenstein 3D. I insisted that something like that, that moved smoothly at your command in any direction instead of in clunky 90° turns and blockwise steps, was impossible with the current technology.
I was wrong.
you were right, the computers couldnt do the math in time. the trick was to precalculate the sin/cos tables for angle steps into tons of lookups instead.
It wasn’t just the trig tables, but realtime raycasting altogether felt like sorcery.
And was re-released last week. I was pleased to see the 2024 console ports still support LAN play.
