“Already” is doing a lot of heavy lifting, by the time the game comes out it will have been 9 years since Civ 6. That’s 3 years longer than the gap between 5 and 6 which is the next longest gap in the series. At this point they’re vastly limited in the things they can do without a complete overhaul on base mechanics we’ve been playing with for nearly a decade.
Would you rather they completely overhaul the current game and the original mechanics be lost to time? Of course not, the obvious next step is to make a new game.
There’s an app, and I’m sure others like it, called Tidy Panel that lets you block notifications based on the content they have. The free version let’s you block a handful, but you need premium for unlimited. For you, the free might be enough.
