Crescenta is a semi vanilla worldbuilding and geopolitical roleplay server where players actually run the story. The world is called Gary and it is about 8 months old. The server is meant to last for years so it feels like you are joining early not late.
People here do roleplay and writing and lore plus politics and diplomacy. PvP and military planning matters a lot right now since the power balance is uneven and new fighters can change the map. Builders also fit in since nations need style and good looking towns.
Moderation is kept minimal so players handle disputes and wars and drama on their own. If you want a guided and scripted experience this is not really that. If you want choices with real consequences it is.
Protection uses the Citadel reinforcement system. It is block by block instead of chunk claims and it rewards smart building and preparation.
There are established nations that take new members and they already have culture and politics going. You can also try to start your own but it sounds like you should not do it totally alone. Versions listed are 1.21.10 to 1.21.11 and it supports Java and Bedrock crossplay. 16 plus is preferred since chat can get pretty mature.
