I usually do buy some of nintendos published games mostly the series I'm into a lot
I buy and keep - ( Smash, zelda, kart, 3d Mario, splatoon, Xenoblade games, mainline pokemon games, donkey Kong country )
I love these game series and have a hard time letting go lol.
But other series like metroid, animal crossing, NSMB, star fox, captain toad, arms etc or other series I'm not too interested in I don't buy full price on. I usually rent these games for $5/$6 a week and return them when my rent is due from my local Video store that rents all the new releases.
As a kid I hated Nintendo's prices cause my parents wouldn't let me buy games and I didn't have a rental store near me. But now it doesn't really matter
