This game is magical to me. There's no other way to describe it. I remember rushing into the store that Saturday morning, bringing it back home, and getting teary-eyed upon booting it up (and then learning that it went out of stock all over town until the next week). It sounds a bit silly honestly, because nowadays it's easy to forget just how big of a deal it was for Pokémon to go 3D. And while we all grown to take that for granted, I still get emotional whenever I start playing this again, because it's such a special game.
Speaking of which, I did actually replay it this year, though it barely feels like it because it was in early January, which feels like a longer time ago than last year. I was going on a trip and decided I wanted to take the 3DS and play a randomizer of Pokémon Y. But when I turned the game on, I realized I'd screwed up the modding stuff, and was left with the vanilla game for the whole trip. Oh well, guess I have to replay this same game for the millionth time. I'd be lying if I said I enjoyed it as much as the previous playthrough, but in all fairness, most of the negative feelings I had while replaying it were just frustrations over where this series went after X & Y, not issues with the game itself. I mean, basically there are things I wish this game was better at doing, but I give it a pass because it was the first step forward in a lot of those things - I expected the franchise to then continue moving forward, rather than taking steps back, but anyway.
X & Y are amazing. I'll always love them dearly, and I'll always feel sad for those who don't. It has one of my favorite soundtracks in all of gaming. In Pokémon terms, it has my favorite region, and my favorite cast of creature designs by far. It was a game I spent hundreds upon hundreds of hours in, because of how much fun it was to breed competitive teams and battle online. It was everything to me for a while. And after that while, it has stayed in my heart forever. Honestly it's hard to explain why I love it so much, but I do. And I'll never let the internet tell me otherwise.
