I regret spending money on this game. I was a big fan of both Pokemon Sword/Shield and Legends: Arceus, and this game feels like a major step backwards from both of those predecessors. The graphics and performance issues are major problems, but everyone knows about those already so I won't dwell on them. Even if these games looked like Elden Ring and played flawlessly at 120fps, they would still be horribly designed.
It feels like Nintendo jumped on the open world trend without understanding anything about what makes it good. Massive expanses of unique landscapes that are filled with redundancy. The game wants you to explore, but does nothing to incentivize it. You may find a unique Pokemon or rare item, but more often than not you find masses of the same 5-6 standard Pokemon of the area and mundane items you can buy cheaply at the Pokemon center. The towns are full of doors you can't enter and a variety of stores with inventories that could easily be compressed into a couple. Nintendo created a massive empty world and filled it with redundancy to trick players into thinking it was densely adorned.
The ability to decide your own progression is a great idea, but terrible in execution. By the time I fully explored the area around the first titan mission and went to go to the first gym, I was already severely overleveled, trivializing an already insultingly easy game. The budget was blown on a few key character models and the rest are forgettable throwaways in another of Pokemon's traditionally abysmal stories. Aesthetic qualities are personally subjective, and I'm far from a hater (I enjoyed the majority of new designs in generation 8), but I find about 90% of the new pokemon designs absolutely hideous. The three starters were promising and likable until the second they evolve, and any google search will pull up loads of fan designs that surpass Nintendo's own.
If I had to describe these games in one word, it's "LAZY." It's too late for me having already purchased it, but if you bothered reading this all, save yourself the time and money, and hopefully Nintendo will realize that they need to stop coasting on Pokemon's reputation and actually put work into their games if they expect them to stand up with the other massive titles being regularly released by their competitors.
