It may be Pokemon's first foray into 3D, but that aspect hardly matters when compared with all of the other things Game Freak added to Pokemon X and Y. Other than a hiccup with a game-breaking bug in Lumiose City (which has since been fixed; if you haven't downloaded the patch yet, it's on the Nintendo eShop), the game is solid.
The game tried a few new things. Some worked fantastically, others didn't. First, the story is still pretty weak and predictable. I still find Black and White to have the most complex plot with the most interesting characters. The issue of handling Pokemon as captive tools meant for the equivalent of dog-fighting or rather their handling as a trainer's friends could have been handled in a black-or-white way. We find N and the player on different sides, and yet N changes -- and hopefully the player's outlook was also impacted by N's words.
But that's enough about Black and White. In X and Y, Team Flare (possibly a pun on "flair") couldn't be more black and white. Even before the player learns much of Team Flare's leader Lysandre, he talks about beauty and his worries for the world. He lacks complete subtlety, and it's hard to see how Professor Sycamore never saw his friend's betrayal coming. When the final confrontation with Lysandre comes, he boils his argument down to his belief that there is so much ugliness in the world, and in a world where people treat Pokemon as tools, all Pokemon must be destroyed to save them. There is no room to empathize with Lysandre because he is a flat character capable of no growth.
We do get introduced to a giant, however, who has had his own ancient morality struggle with Pokemon. The player sees very little of this man, and yet he receives more character growth than Lysandre could ever hope to have.
Game Freak took a different turn with the rival character in X and Y. In the past, Pokemon games have one rival. More recent games have added two characters you occasionally battle. Sometimes they're both rivals, sometimes they're also friends, sometimes one is a great battler while the other finds other ways of enjoying a journey with Pokemon. In X and Y, you travel with four other characters. One is clearly your rival and the next best at Pokemon battling. The second is a friendly girl who you spend a decent amount of time with journeying through forests and routes or keeping each other company while watching the fireworks. The third loves to dance and isn't so good at Pokemon battling. The fourth also isn't good at battling and has decided his goal is to fill the Pokedex, and he will challenge you to see who has more entries in the Pokedex. You both travel on your own and with these four characters, meaning you get to choose to move at your own pace and also battle some recurring characters a few times. The rival, named Calem if you chose the female protagonist and Serena if you chose the male protagonist, and Shauna are with you the most of other characters, and these two become a bit more complex as you learn more about their goals for their respective Pokemon journeys. However, these characters are still fairly simple-minded. Even if Pokemon is traditionally a game marketed to children, there is no need for such simplistic characters in a story. Before people come in and say, "But you don't play Pokemon for the story!" I want to say that people choose their own reasons for playing a game. The beauty of Pokemon is that it feels like your own story. My favorite part of starting a Pokemon game is starting the journey, picking my starter, and catching my first few Pokemon in a new region with new Pokemon. I also get to choose which Pokemon to use in my party, which strategies to employ in battles, and what to name my Pokemon (if I choose to name them). At the same time, the plot of Pokemon games is linear. You are guided to which towns to go to next, which gyms to fight next, and to pursue whichever nefarious team is trying to hurt people/the world/Pokemon. With six generations of Pokemon games out, it's time for more stories that challenge the way you think about Pokemon.
Customization was one of the most fun additions of X and Y. I knew as soon as the clothing customization feature was announced, I would end up spending much more of my money in the game on clothes than on items actually useful in the game. Various styles are available, meaning girls can dress up in cute, frilly clothing or wear a t-shirt and shorts, or wear a combination of styles. However, I wish gender fluidity had been considered in this customization feature. Rather than restricting female protagonists to women's clothing and male protagonists to menswear, players should be able to choose what they want to wear regardless of gender intended for the clothing. And I don't mean "unisex" as in girls can wear the boys' clothing, but boys can also wear skirts and dresses, clothing traditionally considered only for women.
We finally got the option to change skin tone at the beginning of the game, something Game Freak should have had in the games before, but I am grateful for the inclusion of not only PoC NPCs but also an option for the protagonist to be PoC. Thank you, Pokemon for this late but well-welcomed addition!
The other great feature is the online interaction with others. I have rarely connected to the internet in Pokemon in the past, usually only using it for the GTS occasionally, but for the first time I was trading and battling with strangers. The game even encourages you to interact with your friends and strangers playing Pokemon X or Y. You can use O-Powers to strengthen your Pokemon's stats or increase your capture rate, as well as many other things. However, they cost more to use on yourself than others. By using an O-Power repeatedly, its level will increase. Because they're cheaper to use on others, the game encourages you to help others out online. You can also trade with someone, battle with someone, connect to the GTS, or do a blind trade. All of this is easily accessible on the lower screen of the 3DS.
Two other additions can be found on the bottom screen. By pressing L or R, you can navigate away from the online capabilities of the Player Search System to Pokemon Amie and Super Training. Pokemon Amie lets you pet your Pokemon, feed your Pokemon, and play three mini-games with your Pokemon. You don't have to do this, and it's never forced on you, but some Pokemon need to have a high affection for you before evolving (this is partly how Eevee evolves into the new fairy-type Sylveon). The mini-games can take less than a minute, so they never take too much of your time. Super Training is not nearly as cute; instead its purpose is to give you some control over which stats you want your Pokemon to improve. By playing short mini-games in which you shoot soccer balls at targets while evading balls shot at you, you can choose which stat to increase. If you don't feel like spending too much time on it, your Pokemon can hit a punching back once a minute to increase stats.
Overall, Pokemon X and Y is just as addicting as any other game in the series, and with the inclusion of Red and Blue starter Pokemon and some subtle throwbacks to Red and Blue (including a sleeping Snorlax blocking your path and a building with arrow tiles that spin you around), X and Y are a great reentry into the series for anyone who hasn't felt like playing Pokemon since the golden days of old.
