Very happy about the Gen IV remakes. I find it funny how some people are unhappy with the way they look, complaining that they should like Sword and Shield, despite the fact that Pokemon Omega Ruby and Alpha Sapphire was also done in a similar and looked nothing like X and Y. While, I'll admit, seeing Diamond and Pearl in a similar style to Sword and Shield would be awesome, I'm actually glad that the remakes will be faithful recreations of the originals.
Also, since they're supposedly faithful to the originals, we might get the battle frontier in these remakes, something that people have been wanting for quite some time.
I'm also extremely happy about Pokemon Legends Arceus. I takes two of my favourite things, Pokemon and TLoZ Breath of the Wild, and blends them together beautifully. I am curious as to how big the game will be but based on the fact that Pokemon has outsourced development of the Gen IV remakes, and the fact that Pokemon was willing to reveal that this game would come out fairly quickly after the Gen IV remakes, something that could potentially hurt the sales of the remakes, it would seem that most of their effort is going into this game, which is great. Definitely can't wait to see how Pokemon's first true open world game goes, because it looks amazing.
