Yes that's right. After getting the game when it first came out, I finally beat Sin...
Having the official guide, I'm aware their is way more to do. But finally I did it. I was bored
and my cousin was using the net, so I pulled out FFX. I was going to train so I could beat Sin
because I didn't think I'd be able to, seeing as my characters are way weaker than what is reccomended. I versed sin and I won, I couldn't belive it. I only versed him because I wanted to see how much more training I needed... My stradegy? Auron, Tidus and Rikku, as well as a bit of Wakka every now and then...
In the final battle against Sin's head. I was happy that I got that far but I knew I wasn't good enough to take him down before he overdrived me to hell. Well I found out I had twin stars and I used that to reduce mp cost to zero. Having JUST given Auron quick hit and having Tidus also have it. Along with Hastega and no mp cost, I quick hitted the hell out of sin!
Nice?
P.S. His overdrive was like 8/10 full when I won *wipes brow* phew!
