Rolling is the whole fantasy
Katamari Damacy · Super Monkey Ball · Marble Madness · Rock of Ages

Built around plastic music peripherals
Guitar Hero · Rock Band · Donkey Konga · Samba de Amigo
hard
Progress comes from learning how the world works
The Witness · Fez · Animal Well · Void Stranger
These games do not just ask you to solve puzzles. They teach you a language of rules, then dare you to notice what else that language can do. Progress feels like understanding the world a little better, then realizing the world is still ahead of you.

Dr. Langeskov, The Tiger, and The Terribly Cursed Emerald · Little Misfortune · There Is No Game: Wrong Dimension · The Beginner's Guide
