That’s alright too. I just really wish it had the style and fun of the wii and wii u’s menus.
These menus have been fun, but I think being able to boot the console and get into a game within 10 seconds is worth much more. I actively dreaded playing games on the Wii U, just because it took so long to boot into them. The only thing I really want changed with the Switch Menus is the terrible performance on web-based applications like the shop.
