This one thing I've always admired about Nintendo. AFAIK (totally my imagination), the game dev team makes whatever they want and then they tell marketing "YOU WILL MARKET THIS AND MAKE IT A HIT!"
Examples might be Splatoon, Animal Crossing, maybe Smash Brothers, Pikman,
Where as I've been at plenty of companies where marketing effectively says "This is not a Call of Duty/GTA clone therefore it won't sell, therefore we will not waste time marketing it".
