From all Final Fantasy Series, FFVII has been choosen as the best of them all... and that is one reason they are re-making it for playstation 3. Because people couldn't play it for playstation 1 since its almost not in-sale anymore. FFVII is my favorite also... Cloud... Barret, Vincent (Ftw), Red XIII and Cid were my favorite characters following by what makes the game fun (MATERIAS!!!) I love them... Blizzaga, Firaga, Thundaga, Poisona, Poisonga, Stop (Ftw), Regen (Ownage), ohh i cant forget Knight of the Round (1 Shot Kill) also the bosses, Reno, Heiddigger, Reeve, Jenova, And Sephiroth inside the ship of a city that I forgot what was called (Costa Del something...)
From FFVIII another one of my favorites we got Squall, Zell (ftw your punches Limit Breaks Rock) , Irvine (Gotta be fan of gunslingers like Vincent too), and also the Summons (Odin, and some others), and the boss of the first mission which is insane but its fun beating him up, escaping from the machine, and the most annoying part... savingRinoa on the space... I took 1 hour to get her on that time.
FFIX gotta love the storyline... same for FFX and for the great FFXI which was made into an online game.
