Agreed.
It's not just games either. Most software is this way now. Try navigating your way around newer versions of Photoshop, Cinema 4D, After Effects, or anything these days. New features will be introduced but if they're not readily apparent they can go unnoticed for years. The only thing that really does get noticed is when they take familiar items and rearrange them. It's like a game trying to figure out what was changed and what hasn't.
