Ahah, this one, I find particularly awkward. My favourite 3D transitional console/games have to be the Sega Saturn. The PS1 and N64 both used proper triangular polygons, so they looked as we expect to see the average 3D game these days. The Saturn's quad-poly setup made the games look particularly peculiar to the eye today, especially when the camera was focusing on close-up polygons. Some games looked absolutely beautiful (Sonic R comes to mind, Burning Rangers, as well...anything late in the system's development) while some games looked very awkward, especially compared to their PS1 counterparts (here's looking at you, Tomb Raider). Back to Marathon, it's character sprites looked particularly 'pasted-on.' Doom's enemies, for instance, seemed to be designed to be less human-like perhaps so they'd look less shit in 3D (those demon-eye monster things come to mind). Other than that, Marathon is just Doom II, graphically.
