Let's put things in perspective: this game is way too expensive on its own for the amount of playtime you get in return.
I am confident that most of the people who bought this game on day one thought that Morales could have easily been a DLC for the previous Insomniac's Spiderman.
BUT, you get a PS Plus Extra subscription and you're no longer restrained by the full price, and you get to see the game for what it is.
Miles Morales is a milestone (no pun intended) for character movement & animation.
Combat just works, it's really satisfying and harder than it was on the first game.
Plus, the game has a good story, nothing too impactful but it's well-written for sure. Costumes are beautiful, the skill tree is meh taking in consideration that you start the game with most of the skillset of the previous Spiderman.
After-game missions are a bit repetitive, swinging around to get there isn't. There's something incredibly pleasant in the movement, you really don't get tired of it.
Spiderman swinging has never looked this good, and I hope Insomniac keeps up with the great quality.
