If someone stopped me on the streets, begging me to give him the name of the gamest game, I might have to tell him Katamari. Why ?

Katamari takes on a simple concept, you roll a ball on objects and it gets progressively larger, leading to rolling bigger items etc... all while executing the idea perfectly, keeping it's simplicity while brilliantly playing around it. In a way it might also be the best take on the arcade genre.

It never felt so good to progress in a video game, and the final levels of the game are something that you'll only experience here.

Now let's talk about the Artistic Direction : Couldn't have been better, every object has its own unique charm, the levels are perfectly crafted and looks cute, and the soundtrack is one of the best things that happened to video game music having its own Frank Sinatra impersonator on one of the tracks.

Now mix all of that, and you have the best cocktail ever.
Katamari managed to encapsulate all of this into a single game, with the perfect amount of everything and with every single parts tied together, all while crafting all of its elements with the same amount of love.

And that's why Katamari is the gamest game, because it takes on a simple game idea, and do all that's possible to elevate it without altering its core concept.

Play it and you'll understand.
