I've got a list of games I think people should play but it's just based on my opinion only. I also listed what console I played it on.
- Harry Potter: Quidditch World Cup (GameCube)
- Luigi's Mansion (GameCube)
- Super Mario: Two Thousand Year Door (GameCube)
- Luigi's Mansion: Dark Moon (3DS)
- Super Mario 3D World (Wii U)
- Super Mario Odyssey (Switch)
Super Mario World for the Super Nintendo... While it can be rapidly played through (if you're a pro) it's just too classic for people to not experience.
At least one game by Rockstar, preferably one of the earlier Grand Theft Auto titles. I would presume that a large majority of gamers have done this already but those that haven't are definitely missing out.
