sadly it was like this when i saw it, its basically the release titles for the Wii U, Switch and Switch 2.

For the Wii U it had 7 mario games, for the Switch it was 6 plus 1 zelda game and the switch 2 5 mario games (some dont see yoshi and dk as mario games tho) plus 2 non mario games

its making fun of mario fans (plus smash bros fans) in twitter who complained that nintendo was forgetting about mario
