Westworld/YMMV


 * Canon Dis Continuity: The sequels Futureworld and Beyond Westworld.
 * Ho Yay
 * Narm
 * Older Than They Think: Osamu Tezuka actually came up with a very similar premise over a decade earlier for an episode of Astro Boy entitled Robotland. Not only that, the aesthetic of the park is suspiciously similar to the "Murder Game Room" from the late 1960s Sankei Newspaper Astro Boy serial, right down to the cowboy costumes. Tezuka himself points out the similarities in his introduction to the trade paperback in which the Robotland story appears, where he dismisses it as mere coincidence rather than a deliberate ripoff.
 * Uncanny Valley: The disassembled robots.
