FFX has been released in Japan, which means there will be a good flow of FFX news. This news tidbit is definately a spoiler, so only read if you must!    *SPOILERS*     *SPOILERS*     Tidus and Auron:Auron is sort of 'Senior' to Tidus. In the opening when Tidus is playing blitzball, 'Sin' (the terror from the deep) came and destroyed the city they are in. Tidus and Auron were sucked into some water floating in the air and wake up separated from each other, but later Tidus meets up with Auron.  Yuna, Wakka, and Summons:Yuna is supposed to travel around the world to visit summoners temple to get more summons. Where she is also supposed to get the ultimate summon to defeat Sin. And Wakka is going around to challenge other teams of blitzball.  Battle System:Combat in FFX has a new feature, you can now switch party members during combat by pressing L1.   Tidus: somewhat mediocre in everyway, second good fighter to Auron, but can use time spell in the early stage. And he has a very important skill: retreat.  Yuna: Good for only her cure spell and summon spells. Her attack will almost always miss and does little damage (less than 30).  Wakka: Has a ground to air missile launcher, OK against ground, but VERY good against flying stuff.  Auron: A Strong fighter and his weapon has penetration power that ignore's monster's armor.  Kimari: Mediocre Fighter/Mage but is useful for monster information. (he can see monster info, hp, weaknesses...)  LuLu: Strong spellcaster, as spells will normally do more damage than a sword. Her attack is cute (her doll will walk to the monster and kicked it, than run back to her)   info from  FF10sion!
