Doom 64 takes most of Doom II's added mechanics—some of its enemies, the super shotgun—and reuses them in a game that hews closer to Doom 1's level design. Tight, packed labyrinths—although smaller ones than in Doom 1—define Doom 64. It's everything a sequel to Doom 1 should be: its level design ideology infused with new enemies, new weapons, and better rendering tech.

Can't believe I skipped this for 20+ years on the mistaken assumption that it was just a port of the original. It's no port; it's the second best Doom game released in the 90s.
