did you use a random or pre-selected seed?
did you allow friends or play solo?
will you reset chunks to make room for new biomes/terrain features with updates?
what mods did you use?
what difficulty did you select?
what gamerules did you change?
how long has it been going?
I’ve had a few “forever” ones that fizzle out over a few years. First was started on a random seed, no cheats, no mods, standard difficulty level, with 5 of us playing. Over time we granted teleportation as the only cheat.
Second world was almost the same setup with a different group of people but in addition to teleportation, creative mode was allowed for building only.
Played a few with me niece and nephew where they were on tablets. The adults were allowed to use cheats mostly because the kids couldn’t figure out how. We were just using them mostly in build mode to hide things because the kids kept stealing our diamonds or setting our houses on fire lol.
