As a player, have you considered how the game company "preserves" the game IP? In fact, for every gaming IP, how to maximize the life of the IP has always been a subject that all developers are working to solve. The "preservation" mentioned here is not a straightforward IP extension like "Wolf Wolf" to "Wolf Wolf Racing". Of course, this is a proven method, but a failed attempt is very useful. It may cause considerable damage to valuable IP. The collapse of "Artifact" is probably the most unforgettable lesson of V company in IP expansion. So in the game industry, which one has the longest line and the most successful sequel "freshness" experience? That's right ~ it's Nintendo.
