I'm someone who isn't constantly looking for new ways of things being done, moreso just more things to experience what I know I like in.
Example would be dark souls. I could play an infinite number of darksouls games without combat ever changing so long as the zones and enemy models are new. Weapons, armor, etc would be appreciated but not necessary. New spells? New stats? New interactions (other than just the pattern differences between enemies)? Nah.
It's like a sport. There are only so many ways to interact with a ball. The "combat" aspects of sports never changes. It's the opponents. The slight differences in situation to situation that make them great. No new mechanics at all basically ever.
