Help with getting into the game.

Well i install games on my hard drive all the time if you really did install a game go look in memory then to games then find the game you want to play and press A if it says installed game then put the disk in and your fine

I don't and I was just tryign to make my own assumptions of what would be good idk i had the right ideas kinda, but wasn't sure what Serah did the most damage as cause I thought comm always did the most damage for all characters when the target is staggered.
And do you have any ideas on what monsters I should use? I saw some guy with a berzerk and was amazed he had it considering when I saw one he backhanded the snot out of me.

If you plan on maxing all Roles. Stats will only depend on how early you have unlocked the Role Bonuses. I personally unlocked all roles first, then 2 ATB segments for Noel and 1 for Sarah. From their I'll apply the role bonuses. Level Noel in Com, Sen,
Syn. Noel's Saboteur Crystarium also has decent ST increases from level 50 to 99 which require expensive CP costs. For Sarah, level her in Rav, Sab, Syn. Sarah's Sentinel Crystarium also has decent Magic increases from level 48-99 which again requires a good
investment of CP.

Consider purchasing the Official Guide if you are concerned about character development. Also focus on obtaining Noel's Curaja spell. He is the only one who can use it and it makes him a better medic IMO.

saboteurs in ff13 were the same, debuffing is basically a chance to happen or not. it balances it out so you cant just instantly debuff. some enemies could also be more resistant to certain debuffs. to make it easier have 2 saboteurs. 1 as serah and 1 monster
who is a saboteur. and noel as tank so he attract attention and defends while you debuff the enemies. bosses are always more resistant to debuffs and sometimes immune.

Serah wouldn't do more damage even if I have her magic skill higher then her strength skill? and I beat the boss, its just that boss and one of those half looking creature bosses completely tore me up and take me a good number of tries before I killed them
like it wasn't one and done.
