I'm...sort of indifferent about the whole affair.
I played the original Pokémon Snap when I was younger and it was
fine, but it was never really my thing. I know a lot of people are excited about it, including people in my general social circles, and I'm happy that they're getting the new Snap game they've long desired. It's not something I'm interested in purchasing though.
With Brilliant Diamond and Shining Pearl, I really dislike the chibi artstyle and the camera angle for the overworld. I appreciate that they're seemingly being faithful to the originals by referencing how the old games portrayed things, and usually I'm more on board with being faithful with remakes and adaptations, but I really dislike the chibi proportions making the player characters look like they're three years old or something. I think I was expecting more modern proportions like were present in Sun, Moon, Ultra Sun, Ultra Moon, and Sword & Shield and with a camera angle to match. At least they look like what you'd expect when they zoom in for Pokémon battles, but I just wish that was their default, you know? Regardless, artistic decisions aside, I'm very glad that they are traditional and faithful in the other regards and that they're not Let's Go games. The Sinnoh experience present in Diamond, Pearl, and Platinum is among my least favorite (aside from Kanto, which has been beaten into the ground with overexposure throughout the decades) as things currently stand, and I've been open for years to the idea of experiencing it revisited in a remake to see if my opinion might improve with the advancements the series has made since then.
I will say though that I'm pretty unenthusiastic for a few reasons, but one reason stands paramount. The way I've approached Pokémon games for over a decade now is that I decide on a team I want to use for the playthrough of a game, and up until Sword & Shield and its removal of the National Pokédex and culling of a large number of Pokémon,
I had the ability to choose any Pokémon from any region up to and including whatever generation game I'd be playing. I think the ability to do that is part of what kept me invested in the series longer than I might otherwise have been, and that freedom of choice to use any Pokémon on any team being absent now kind of sucks a bit of the fun out of the Pokémon world. From things that members of Game Freak have said, I have no expectation of them just bringing everyone back into the fold under one roof due to the design philosophy going into the game making these days. As a result, unless they reverse course, however good these games might end up being, they won't be the games I would've ideally wanted them to be. I'm not writing them off entirely, but yeah, I'm not excited either.
Pokémon Legends Arceus looks...interesting. The premise is neat and I can see some potential there, but as LuchaSloth said:
As for Arceus...it just looks empty. I want to give it a chance, but I don't think they should have shown this one yet. Either it's so early in production that they haven't added final touches...or it's just going to be a very stark game. Very reminiscent of the open world of Sword Shield...but, honestly, somehow emptier. Just a very void and muddy look with very little going on...
It frankly looks sparse. It's still too early for me to say much more than that. I'm open to seeing how it ends up.
For both Brilliant Diamond & Shining Pearl and Pokémon Legends Arceus, I'm going to refrain from buying them at launch and am going to wait to see what people think of the games and what sort of consensus can be formed. There's not much I like about Sword & Shield and the decision-making at Game Freak and The Pokémon Company International, so I'm wary and want to stake things out.
