We used to get yearly Final Fantasy games and a new main Elder Scrolls title every 3-4 years. Now, games take over a decade, and have no focus on worldbuilding or gameplay. Why? Because primarily high intensity graphical requirements for a marketable game. I have never met a man who demanded 'pretty graphics', yet I have never met a woman who will play a game older than Skyrim because they're 'too ugly.' (Exceptions are if they grew up with the game, like WoW)
