Tron is about this guy who gets sucked into what I can only describe as a sh*t-ton of software as a program and is forced to compete in "games" as punshment for i forget what there were no subtitles (if you say "I've played these games before" I swear to god)
Pixels is about when arcade games first started, but the US sends some videos of an arcade championship to outer space, and aliens take it as a threat and send warriors themed after those games to earth
TL;DR: Arcades, but you can die.
