Back to fun hardness of video games! We'll prove a bunch of “metatheorems”: video games with a few basic features are NP-hard or PSPACE-hard. Then we'll apply these metatheorems to prove NP-hardness of Boulderdash, Lode Runner, Zelda II, and Pac Man; and PSPACE-hardness of FPSs (e.g. Doom), RPGs (e.g. Eye of the Beholder), adventure games (e.g. SCUMM), Prince of Persia, Legend of Zelda: A Link to the Past, Donkey Kong Country 1, 2, and 3, and Lemmings. | |||||
