I don’t know, games like Minecraft, Factorio, Satisfactory, Rust, they all have a lot of staying power. There’s always burnout but I don’t think that Palworld is going to survive to the “We should go back to that” stage.
I burnt out on Factorio after I had fifty ion cannons in orbit and a few battalions of remote controlled mammoth tanks. It got boring after I had finished everything. And restarting was too daunting.
I’ll definitely be back for the big update though. The new trains look incredible.
Personally I do think palworld will survive though. The core loop of capturing pals, leveling, and attribute hunting, is very fun.
