Naming a ‘best’ game is tough, because it assumes that games are only consumer products, when so many times they are so much more. So, I think I just need to go with my gut, which says that it has to be WarioWare, Inc: Mega Microgames.
It encapsulates the things I love most about videogames as a medium: fun and thrilling, it has so many styles in its expression, and it never assumes that the player is dumb; with one single word, it teaches players its rule for every microgame. I find that design to be incredibly impressive. To this day I’m still fascinated by how
WarioWare, much more than any other game, feels like it has its own agenda, and just races forward, even when the player fails, which never makes it dull.
And, most importantly, it could never be the best game if it didn’t deliver in emotions: WarioWare is perhaps the only singleplayer game that makes me laugh out loud.
