Yes, you are right that playing a game with infinite ammo and health is boring.

However, this never happens in the real world: You buy a nice car, then a nice house, then go to nice vacations, eat better, healthier food.

Then you realize that there are layers of nicer everything above what you consider "nice". Build a more ambitious company, and end up building rockets to explore the solar system and make humanity multi-planetary, cure illnesses, extend knowledge or education or peace.
