If you want to play Super Smash Bros. Ultimate with a GameCube controller, as nature intended, you’ll want to preorder the controller and/or the official adapter now. Not only are they in stock (hardly a given with Nintendo hardware), Amazon’s actually taking a tiny bit off at checkout for each, no Prime membership required. It’s not a big discount, but it’s better than nothing.
Note: If you have the original adapter for the Wii U, or any old GameCube controller, those will work too.
Prime members can also preorder and save $12 on the game.
Grab yourself a Ridley Amibo while you’re there. You know you want to.
