Final Fantasy X Walkthroughs
Final Fantasy X is the first FF game for the Playstation 2 and the first of the series to have voice over acting as well as many other modern day features we've grown accustomed too. This game also takes away many of the traditional Final Fantasy features we're used to such as walking on the world map and being able to fly an airship around the world manually.
Final Fantasy X also doesn't have a traditional leveling system but rather a Sphere Grid which will control the advancement of your characters. The last thing worth mentioning is that this game is much more tactically oriented than your average RPG as well as most previous Final Fantasy games. You're expected to cycle through almost all the playable characters you have during each battle.
I have quite a few guides for Final Fantasy X that you should find helpful; my most useful guides include a walkthrough for all of the Celestial Weapons as well as the Monster Arena and all optional Aeons.
The guides I have don't stop there though! I also have guides for the Airship (passwords and locations), Key Spheres and where you can find the ones you need. There's a guide for Blitzball and finally a guide that'll help you cheese filling in all of the spots on the Sphere Grid and maxing out your character's potential.
