Core gaming is usually associated with one or multiple points of the following:
* learning needed to play
* skill needed by the player
* more time needed in single sessions (casual games can add up to a lot of full playtime, but you can play a 10-minute-session)
* something that has to be remembered over the full game (usually storylines, but also other stuff that makes it hard to pick up playing in the middle after some months)
* higher difficulty
