I just looked up the elephant vs mouse segment. The way the elephants reacted, I kinda feel like they’re being cautious because they recognize a harmless lil animal and don’t want to step on it. Like they behave pretty much exactly how I do when I see a little spider or frog or cricket or something. like “whoa there buddy, you dont wanna be under my feet”
Generally games with random elements are considered to be good for dumping tons of hours into. So games with randomly generated worlds like Minecraft, roguelikes, strategy games that are always variant just because of the nature of AI actions always being a little randomized, and other stuff like that. So maybe like Minecraft, Dwarf Fortress, Crusader Kings 2 or 3 as like a basic list. But really the game that’s going to be the most replayable is the one you don’t get tired of. I’ve beaten Thief: The Dark Project hundreds of times and that game is a relatively simple level-based stealth game with no random elements and not even especially huge levels.
