Why do companies even make core games?

The core gamer is not the heart of the gaming business, it is the masses. It's a simple business rule, if your market is 100 people large, and only 20 of those people are 'core' gamers, then it is logical to spend more resources selling products to the other 80 people.

...

just because only 20 out of 100 people want a "core" game doesn't mean the other 80 people all want the same thing.  also, don't think of people as people, think of them as dollars.  I buy about 20 games a year while my mom (a decidely not core gamer) has bought a total of 4 games for her wii over 2 years: wii fit, wii play, endless ocean, and deca sports (and wii sports of course).
