I did use a gameshark code in FFX in order to get one of the sigils for Tidus and Lulus celestial weapons (because after 2 hours of trying to get a race time of zero, and another 2 hours trying to dogde 100 consecutive lightning bolts it gets to be a bit much). Besides that i usually just figure out and pass games on my own

Also FFX is much better then FFX-2. FFX-2 had potential but it was never to be used.
