Yeah for an example of a series that has found a reasonable equilibrium there companies should be looking at Civ. By making every game significantly enough different moving to the next doesn’t feel like 20 downgrades to get a slight upgrade, but more like 5 has reached the conclusion of what it will ever be, 6 is now new and will have 2 major expansions and a variety of minor ones, but you only see a bit of how it’s incomplete until years later when you’re reminded that some feature came in rise and fall and you’ve just taken it for granted for several years.
