I'm playing through X on the Switch. I think I'm almost done... I'm in the Zanarkand ruins right now. The track "A Fleeting Dream" just really hits me for some reason. So powerful. I've enjoyed the story so far, the characters (Auron is pretty darn awesome), the soundtrack. Not flawless game, but a phenomenal experience. I am really excited to start other titles in the series, but I worry they won't be as good.
Just thought I'd leave this post. I freaking love this game and am grateful that it is on the Switch, otherwise, I would have never played it.
It's a great game, one thing to bear in mind though is, for many people, their first FF game becomes their favourite one. So bear that in mind if you're playing the others and they don't seem quite as good, it's probably not their fault, it's just that you already got hooked on another one.
The Zanarkand ruins section is pretty memorable, the game feels like it was leading up to this moment, this moment that was shown to you right at the beginning with everone sitting silently around the fire. Then when "A Fleeting Dream" kicks in...it's such a great track and the way it continues to play throughout the battles is an effective trick that many other FF games have used, it works every time.
Personally, FFX is in my top 5 FF games and I'd strongly recommend playing some of the other games, since you have a Switch, FF7,8,9 and 12 are all good games and within what I consider the "golden age" of FF games.
