>>13824if mods are allowed: minecraft (infinitely replayable once you put 200 mods on it)
if internet is allowed, but not mods: World of Warcraft or Old School Runescape, maybe genshin impact?
(constant updates, people to play with, lots of crap to pass the time)
if neither are allowed: still probably minecraft, I'm sure I could just spend hours building castles and stuff in the vanilla game.
none of these are my favorite games but they're the most likely to keep my attention for as long as possible
