Personally, these two games are my absolute favorites of the entire FF series. They were part of my childhood, and even now I still love them and replay them quite often.
Many people agree that X is a great game; however, there's people who say that X-2 isn't great, that it's too "girly", etc. etc. and honestly, I disagree. Firstly, "girly" isn't a bad thing, I think the reason why people say that is because the main character is a girl, and the 2 lead supporting characters are also girls. Part of the combat system is "dressphere shift" where your three playable characters can shift between their outfits in order to use the different abilities and powers. "Fashion? In combat?" Yes! Think about it, you're changing from different outfits so that they can fit according to your offense or defense. I don't see why this should be a bad thing. Plus, the designs of each outfit are really, really cool. They can be feminine, but again, that just isn't a bad thing. The three women are still powerful, tough, and the battle system is super fun to use. You don't even HAVE to use the dressspheres except for the tutorial, although I would recommend using them, especially if you like to 100% your games. But I'm sure you could beat the game without them. I think. I actually don't know entirely because I've never not used them, but I don't see why you couldn't.
Basically, if you see someone say that FFX-2 is bad because it's girly, just assume it's because they're used to playing video games geared towards the "manly" audience of guys who were taught growing up that being considered feminine or girly is "Gay" and a bad thing. Play the games for yourself, decide your OWN perspective. It might just change your life, or you might get bored from the games and move on. Either way, thanks for reading.
