If you ever heard That You Can play as Sephiroth or Zack who ever told you that was wrong.
The 1/35 Soldier item is usless and the rumor if you collect all 450 soldiers you can get a Sephiroth clone and that isnt ture and you can't get 450 items the max. is 99
If you master the Kight of The Round go back to the cave and you'll be able to fight him(not true)
There are no hidden characters in final fantasy there are only Cid, Cloud, Barrett, Aeris, Cait Sith, Tifa, Vincent, Red XIII, and Yuffie
To get Super Nova Sepihroth's skill on the second disc go to Junon and talk to everybody then talk to Priscilla and she'll give it to you only if you beat both Emrald Weapon and Ruby Weapon
Aeris Cannot Be Revied. Tho she dose help the party out thorugh the game.
