Nintendo is doomed. This is a phrase both Nintendo fans and haters alike have used for many, many years now. It has really taken on a new life thanks to the internet, and now it's become a bit of a meme. Recently, we saw people bringing it up once again thanks to Doom coming to the Switch.
It seems either Bethesda or Nintendo have latched onto the phrase, as you can see it used in the official advert above. Yes, they dropped the "ed" from NintendoDoomed, but this is still a direct nod to the reference. For those wondering, the blurb under NintenDoom reads, "Popular Internet saying."
