6 Month wipes. Set the dates and follow through.
Make a global leaderboard for every stat and every skill that can be viewed by everyone, maybe update once a day to save bandwidth. A cosmetic reward for some categories in the next world, a permanent hall of fame, and so on. Punish the grinders, Bennett Foddy style.
If some of the pvpers quit, wow, you will expand your income exponentially. Not to mention, all the money comes at reset with the returning players and re-subs and so on. How the fuck did we let Valheim and V Rising and Palworld (for fucks sake) blow the goddamn doors off this game? Could have been rich man, but we still think we are gonna wake up in '99 and log into Ultima Online.
Quicker world iteration will allow more drastic changes to be implemented with lower risk. A 6 month world without hunger, a 6 month world without oceans, a 6 month world with random spawns. You could explore more of the design space without feeling hemmed in by the "persistent" world and the need to hold on. Let go or get dragged.
Game is beautiful and I would love to interact with it more regularly. It is a mistake to plan for the players to devote themselves to it forever. This isn't a true love story, it is the turning of the seasons (fuck winter btw).
