It's... really one of my favorite games ever.
I honestly wasn't expecting much, because it didn't seem that crazy in videos, but when I finally played it, what a joy it was.
I'm a huge fan of arcade / scoring games, like Tony Hawk, SSX and all, which don't exist anymore sadly, and I also love fast paced action games. This game is exactly the mix of that.
It's really up to the player to make the game fun or not though, if you decide to do the bare minimum, you can technically just play it like dead rising and it's not really fun, it's pretty generic. But if you want to have fun and embrace the gameplay to be creative, it's an insane game with so much freedom.
I really think this game has the most fun traversal gameplay of any games I ever played. Plus the open world is for once very fun, because it's not filled with boring sidequests everywhere, instead it has a bunch of environmental and various arcade / scoring challenges everywhere which are super fun and so addictive, it really reminded me of Tony Hawk in that way.
It really felt like a game out of time, it's a game from early 2000s, in the best ways, made with modern tech, and it was a fantastic experience. I miss games like this so much, I really was happy to finally be able to play something new like this.
edit: reading all the comments and seeing how everyone think it's trash, it makes me sad
