My personal opinion on Pokemon Scarlet Violet
While I'm trying my best to avoid spoilers, it might contain some info that you might not know yet - please be sure
Visual : Definitely unpolished and unoptimized. The game runs at 3FPS the whole time, sometimes the camera behaves weird, and some objects have kinda glitchy motion that are absolutely visible even from far.
Gameplay : Despite the visual issues - it's insanely fun. Though sometimes we can find glitches or minor issues, fortunately they are all not fatal or major problems to progress the story (as I understand the glitch hunting scene correctly). There are a lot of things you can do, exploration, taking a detour, or just catching Pokemon, all of them are wild. Usually I stop playing after beating the champion, but it's not the case for SV somehow. Though it would be super awesome if the game runs at least stable 30 FPS constantly though. Also Terastal gives it a lot more depth to the battle and the raid mechanics. It's a very simple but crazy idea without exaggerating. Unfortunately we still feel the Terastal raid battle is also not polished while we definitely enjoy the raid with friends or with random people, I just believe they will improve it more in future.
UI / Mechanic : Okay - Meh. Some are cool - like scrolling text is much faster compared to the old titles, it even allows us to completely skip some dialogues that we often read frequently - but some are definitely with space to improve, like the map or the bag. I believe there is nothing really game-breaking, that's at least good and probably they paid the effort to patch out.
Characters : Absolutely wild. Since this is just a personal note, I'm sure I'm just saying my personal favorite - they are all super unique and vivid. I can talk forever about them. Ortega, Grusha, Rika - who hates Rika, Iono - yeah I know some people hate her, I don't actively like her either but we definitely feel like she's a new breeze to the world of Pokemon so yeah I take it - actually all the team star leaders and gym leaders are super cool, I need to appreciate all the designers working on creating them. I really really wish we could meet all of them after beating them since they were toooooo adorable to just fight and bye. Especially the elite four - once you beat the elite four, you can't re-match them for good. Yeah... Rika...
New Pokemon : like how could they think it was a good idea to add just flamingos???? I mean it's funny so I love it though. You might feel some Pokemon are disappointing, like Dudunsparce, or Flamigo, I have no argument with that. But otherwise I feel they are crazy and broken in a good way, like we got chilli pepper, twin-headed chilli pepper, bread-puppy, earthworm, just a rock salt - I couldn't stop making the pog face after finding that tiny mushroom-ish pokemon that I ran into was just a tiny rock salt crystal - tumbleweed, a chibi megaman, two megamans that have flame and sword respectively, and a flamingo. How?? Let me repeat it - I absolutely love these crazy new Pokemon ideas, they make the adventure much more fun to try to find and catch a new one.
Music : Fantastic. I definitely want to point out the elite four music issue - the background music for the elite four battles can be stuck at the intro loop forever and it doesn't progress the music somehow, unless you restart the game. That's... probably one the worst audio glitches, feeling as a composer. Since it is one of the climaxes of the game... Let's forget the bug since I remembered to restart my console before meeting Rika. They are absolutely fantastic. Some tracks even seamlessly continue between the exploration and the battle phase, it makes me - wow. Plus Toby Fox made a lot of more bangers, it would be a spoiler so I don't wanna talk in depth here though - they make me absolutely hype. I'm sure for music - it's easier to understand it by listening, not talking, so yeah I recommend you to check some tracks from it. Oh please be careful the Ed Sheeran jumpscare (I love the song tho).
Story : Holy Dudunsparce. Not gonna lie, this is the first time that one of the main series of Pokemon titles made me cry through the story. Even twice! They really tried and it worked. I mean I know it's kinda cheap, straightforward and very simple because it's Pokemon which has the largest diversity of players, some are not familiar with playing games, or some are literally children, like 6 yo (right?). But dang that was something.
Overall : I think other people already said it, but - it's the most broken pokemon but so far the most fun pokemon at the same time. That's crazy.
