There's joy in trying and discovering how things work in the game. I'm talking about not having retarded modern-game tutorials, like "walk here, well done, now press here, great job, see how this button works, good boy, have an achievement".
In Grimrock 2, I don't feel like the game is treating me like a drooling moron. Instead I get to figure out how the game works, by myself. It's rewarding.
That's all.
