Best Sonic Game in Years
I was hoping this game would be good and it surpassed my expectations by a longshot. This is a massive game with 5 huge open world islands, 4 of which have tons of content, and 1 of which is just there for some great platforming and story. There are 30 levels mixed of side scrolling and 3D platforming, the aforementioned open worlds, tons of mini games like shoot 'em ups, fishing, pinball, and over 100 puzzles. There are some really good mini bosses throughout, as well as regular enemies. The boss fights are spectacular. The story is very good. The soundtrack is excellent. The entire game is very different from the usual Sonic games, in a good way. There isn't any post game content other than what you didn't do on your first playthrough. It takes 12-15 hours to get through the story and over 25 to do everything.
For the negatives, this game has tons of pop in where most objects don't load until you get within a certain distance of them, but nothing is game breaking or too annoying. It's just unfortunately too noticeable and distracting at times. My other complaint is that you can only play as Sonic this time around and none of his friends.
Lastly, the deluxe is only worth it if you want the artbook and soundtrack. There's a pair of brown gloves and brown laced boots which is exclusive to the Deluxe, but the rest is all grindable in game, and the grind is not bad at all. You will have far more of everything than you need as you need it to progress as long as you do some side stuff and exploration here and there and not just rush through.
I would definitely recommend this game. It is easily the best Sonic game in years and one of my top favorites in the franchise.
