Wow, this was a surprise to say the least. I expected a game set in Johto, Unova or Paldea, but instead, it is another Kalos game? Totally didn't see that coming. Talk about a last surprise. It totally crept up out of nowhere. Either way, I'm interested. As I'm one of the few Pokémon fans who loved X/Y and consider them to be the second or third best games in the series, I'm all for another game set in Kalos. The return of Mega Evolution is also really nice as it is my favorite super mechanic. That said, I wasn't overly fond of Legends: Arceus (I thought the game was good, but not great), so I really hope Z-A won't have any of the issues from Arceus. I especially hope they'll keep the traditional battle system, as I won't enjoy the game much otherwise. Or if they are going to change it, please change it for the better, not worse. Here's to hoping.
As for the game itself, there are a lot of things I want to know about. Right now, we know almost nothing. There's no gameplay footage, all we have is the game name, the setting, some Pokémon that will appear, and the release year. Speaking of which, I have mixed opinions about it being released in 2025. I hope that a later release means the game will have higher quality, but with that, I wish it had been revealed at a later point. This is almost like GTA VI. Though, this gives them a lot of time to build up the hype, so I guess that's something.
For now, I'm optimistic about the game, and I will most certainly get it. Looking forward to getting more information about it.
