Nintendo is offering discounts on select Mario games, including Super Mario Odyssey, Super Mario 3D World + Bowser’s Fury, and Luigi’s Mansion 2 HD. The sale includes a unique experience like Bowser’s Fury, which adds new collectibles to the base game. Meanwhile, Steam has launched its summer sale with PC games, offering a chance for gamers to find discounts outside of Nintendo. For those looking to buy on Switch or redeem on their console, eShop remains the best option, while Humble Bundle offers similar prices.
