What five games should everyone play?
Either because they're the best, they are so culturally significant, or otherwise?
Super Mario Bros.
Super Mario Bros. 2
Super Mario USA
Super Mario Bros. 3
Super Mario World
>Super Mario Bros.
For the history
>Portal
Because it's an incredible example of atmosphere, level design, and gameplay.
>Minecraft
It's a shit game, but it's one of the most culturally significant games in history
>Tetris
Same reason as Mario
>ET Atari 2600
Same reason as Mario
Tetris
Pretty much any Super Mario bros game (but especially 1, 3 or World)
Pac-Man
I can't think of an especially significant racing game so...
Something from Square-Enix's hey-day (FFIV-VII, Chrono Trigger, the SNES Dragon Quest games, etc.)
