You don't have to worry about owning amiibo to get costumes in Super Mario Odyssey. On the game's official website, Nintendo notes that "all outfits can be unlocked in-game without amiibo." That implies that even the wedding outfits with the new Super Mario Odyssey amiibo aren't exclusive to the toys. (UPDATE: Nintendo confirmed to IGN that the wedding outfits can also indeed be unlocked without amiibo.) That said, we here at IGN have reached out to the company for confirmation on this aspect. On the flip side, if you do own a lot of amiibo, every single one of them will work with Super Mario Odyssey. Some will offer help, while others will unlock costumes. A couple of months ago, Nintendo caused some confusion with how amiibo worked in Metroid: Samus Returns. While a hard mode wasn't locked behind the toys, Fusion Mode actually was. Over the weekend Super Mario Odyssey was highlighted at the Nintendo World Championships 2017. And IGN's new video series, called Next Big Game, focused on the Switch exclusive for its premiere episode. Source: IGN.com
