Imitation is the greatest form of flattery!

I suppose there's still Quake 3 Arena and DOOM3 to complete the full "John Carmack" early 90s to early 2000s technical overview series.

Or maybe something with the Sega Saturn. I heard the Sonic X-treme team worked so hard to make a 3d Sonic game for that platform in the mid 90s that multiple team members had to go on medical leave!
