Ok, so, I've decided to start a new game of Final Fantasy X before playing X-2. Luckily there's YouTube if I get stuck at all, but since I've got the official HD Remastered strategy guide I might not need to rely on YouTube. Right now I've progressed to the point of the Al Bhed ship that Tidus helps in exchange for a place to stay after Sin transported him to the middle of nowhere. Or seemingly the middle of nowhere at first. I've never actually beaten X or X-2, so I'm hoping to cross that off my bucket list. Tragic story though. I still need to see the end, and I've forgotten a lot of it. That's why I'm restarting it. I'll keep posting my progress as I go trough the story though. Funny thing is I've got 99 Potions already. You just dive until you reach the next screen (underwater above the chain) then swim back up the chain and go back to the ship and the Al Bhed that gives you 3 Potions will give you 3 more. It's probably a glitch, but it'll save a lot of Gil if I just do it that way.
Right now I'm trying to unlock the Warrior and Slayer Overdrive Modes for Rikku and Tidus, getting Blitz Ace for Tidus, and the sphere levels along the way won't hurt.
