Yeah but making it popular doesn't necessarily constitute survival. Hell if anything popularity means it's just going to follow along the common path taken by other games that are made popular and likely lose it's original flavor that connected with the older fans of the series. You might have the younger gen liking it but that doesn't mean the older has to like it or respect the direction the series takes. Hell, a lot of people hate Fallout 3 for the bad story, characters, gun play, and limited weapon and ammunition options. A lot more people hate Fallout 4 for doing everything Fallout 3 did, but worse with only one step forward and 5 steps back. When you go the route of other popular games and adapt a lot of things they do, such a series would lose uniqueness.
