I’ve had an idea for an open world game. Generally, people are “completionist” players that uncover every last rock. But then, they complain that uncovering every rock was boring.
So, the core of the game would revolve around a compelling “ball and chain” that prevents players from being completely free, at least during a first playthrough. You’re required to make steady progress due to story needs.
The idea I have is basically you play as a traveling doctor with a caravan, moving a patient around to new places that might have an herbal cure you need. There’s other adventures to help you, but a time limitation at work as well - just permissive enough to let you enjoy yourself but not to bore yourself through your own grinding choices.
Just the fact that it’s open world means it’ll probably never be made due to budget.
