Very well said! I wish we had a "Pin Comment" option because thats the exact problem that plagues the gaming industry.
Another thing that coincides with what you said is that developers/publishers spam out games, I think there'd be more money to be had if games had longer shelf-lives and better additions. CoD for example, Cold War was an amazing game but its dead now that no content is going to be added, just another battle-pass that is specific to the new game. One of the only times I agree with Rockstar and GTA5, keep the content running and the game will last ages.
I think GTA V is a great example, because even though they gave the game a long lifespan, people is still hyping for the next one. It's an example that an extended lifespan doesn't necessarily mean the death of a saga, and the industry should really learn from that.
