Why do we feel the need to buy new games?

The human brain has one single purpose: to learn. It can't do that when you do just the same old stuff over and over again. It demands for you to feed it new stuff constantly.

At least that's what some anthropologist once told me. =P

I suppose that makes some sense but it doesn't explain why I don't eat cheeseburgers every meal or games that are easy like Walking sims or like I mentioned in the OT, Vampire Survivors cause that's not a challenging genre, the point os to be fun without challenge.
