Tips of FF7,FF8,FF9

Final fantasy 7

Try to keep up, depending o your levels, every time you receive a new item,check it on the inventory,so that you'll know if it's a weapon or not.Every time you receive a weapon, equip it and check the atk and atk%, if the atk is higher than the atk%,equip it.Level up your materias, I recommend that in all the game you equip the restore materia with cloud, don't ever unequip it (unless you are when you don't have cloud on your party),you must level up summons too.

Final fantasy 8

You must know that the most powerful character will be Squall, in all the game,after going to the fire cavern go to Squall's desk and aquire Shiva and Quetzacoatl,then train hard, battle at least 15 groups of the fire fish, (Fastifolcon or something like that are named)to gain the ability to do advanced magic from little magic, so use blizzard and make it a blizzara and you can win more easily to Ifrit,then when Headmaster Cid gives you an item called Magical lamp, don't use it instantly, belive me, he has 16'000 HP, wait a little more.

Final fantasy 9

In this game Im sure you won't need much help, just be aware of the bosses, like the one in the ice cavern,Black Waltz no.1 , he's not very difficult,just when Zidane is in trance,use his attack called "tidal Flame", and the liitle Wizard will be torched,train a lot and be prepared for the whorst...... you'll never know what's gonna happen(unless you have finished the game)
