The Playstation and Sega Saturn heralded the switch of almost every game released from 2D to 3D. A number of game types were sacrificed in the process, only the 2D fighter (Street Fighter Alpha), Side Scroller (G-Darius), and platformer (Oddworld) manage to survive one last generation. To my knowledge there has not been a game with 2D gameplay released on any subsequent consoles.
Abe's Oddysee and Exodus use the Playstation's capabilities to provide rich backgrounds and slickly animated characters, all integrated with seamless cutscenes. There have been no games like them before or since (Munch's Oddysee included). Another World, Flashback, Heart of Darkness, Abe's Oddysee and Abe's Exodus represent the last of an era (and not forgotten by gamesplayers of the time).
