Certain genres would not work as well as they do as open world games. You're asking for too much. If they were to combine all the genres like you suggest, it would have 1 dominant genre that plays well and other, more mediocre, genres that aren't as well made due to the dev team not being used to working on the other genres. Games like what you say will probably come into existence more often now, but I doubt they'll become the next Gen standard genre.
