I'd like to see them go back to treating 3rd parties like trash. Only allow 2 games per publisher per year, only now no satellite publishing to get around the rule. See how much shovelware they make when they only get 2 shots at that sweet, sweet playerbase per year.
If their game is good and performs well, they get to make 1 addition game the next year.
Maybe Nintendo was right in the NES/SNES era in that regard.
