I feel that in a way focusing on titles that have established brands eventually leads to accomplished, veteran developers abandoning studios because the studio gradually becomes an "x factory". My perspective is that it stifles creativity if you have your parent company dictating the ip's that you must continue to make rather than that decision being something that the development team determines for itself. I like Sony's outlook on Evergreen titles, and I'm glad that they grant their studios the freedom to explore ideas at their choosing and abandon successful, tentpole ip's. I'll take that over Nintendo or Microsoft's approach any day. If ND were forced to only make Uncharted games, we likely wouldn't have seen TLoU for example. Some series need to be retired for a time, and when sensible, should be reintroduced to a new audience but with callbacks to entice nostalgic older players.
