Well, the best way is just to follow what everyone is saying. The talking tells you where to go and who to follow. Look in Google for strategy guides and walkthroughs if you have a hard time. Plus you can always ask us here at the boards if you are stuck somewhere. Oh and fight often if not alot. It helps tremendously. ;)
Yes, make sure to talk with everyone you see at least once...maybe more because sometimes you get free stuff....and how can you not want the free stuff? heh, heh. I'm going to move this to the FFX forum. Well, i hope that you enjoy posting and have fun gaming.
Talking to evry body helps you get free stuff like madhtr and gene said. When I first started the game that was what I did. When I started the game it felt like a different style, not a rpg feeling. :D
