Ah, I guess I misunderstood it, then. But my point still remains: Basing advancement in a game off of a completely arbitrary thing, which the player isn't informed about at all, is just plain bad game design - especially when the visual cues placed in the game tell you something completely different.
"'Casual games' are something the 'Game Industry' invented to explain away the Wii success instead of actually listening or looking at what Nintendo did. There is no 'casual strategy' from Nintendo. 'Accessible strategy', yes, but ‘casual gamers’ is just the 'Game Industry''s polite way of saying what they feel: 'retarded gamers'."
