I don’t see why you think this can’t work when the current system has only been in place for the last decade. The majority of things pre-2010 were all “fixed”. If anything, quality has only decreased since then, because companies know they can release the absolute bare minimum, and only have to invest as much as it takes to get the majority of buyers to stop having the energy to complain about it. If that were a fixed game instead, putting in that bare minimum would be a one time event, after which no one would buy from them again.
