FFVII, got all the way to the end, but wanted the best summoning/materia/forget what it was called to beat the final boss... involved lots of breeding of chocobo and racing them. Got bored sick of this, and never went back to the game.
You don't need to breed chocobos. You can go to juno reactor to a screen where you are walking through a glass tube underwater, where you can fight the ghost ship. This ghost ship you can morph into the guide book
. You can trade the guide book for the gold chocobo with an old guy in Calm after meteor appears in the sky.
