It's a Pokemon game with the same formula as always and some welcome changes like the wild area where you can free roam and catch wild Pokemon. You can also engage on multiplayer dynamax battles there. I wish it had better online functionality though. It can be completed in a short time if you grind to level up some Pokemon and take on the gyms. Performance drops quite a bit when connected on-line, so I recommend not connecting online unless you want to play some of the online modes.
Overall the game looks good but not ground braking graphics, not even close. It's a 3 star graphics.
Performance has some issues when online but it never feels unplayable. I think it needs some optimizing, but overall a good experience, 30fps most of the time if not on-line.
After defeating the Gym Leaders, the tournament feels like a fill-in and the plot is underwhelming. You never get to control the legendary Pokemon, which is disappointing.
Overall it's a 4 star game in my opinion.
