I, thanks to rebuying a PS2 and having the PS3 and its PSN, own FF1-FF13 + Tactics and X-2 (minus 3, 4, and 11). I really want to beat all the FF's, not just beat A and B and play a handful of others like I had up to this point. I want to play through the entire game of every game I own.
What are the ways to make these games "broken"?
For any of the above stated games, what characters, set-ups, weapons, summons, level paths, etc should I have to make these playthroughs as easy as possible? I want to get to the final boss and not have to grind for 40 hours or not be able to beat it at all.
For FFXII, look up how to get the Zodiac Spear early in the game. It's very easy to ruin your chances of getting it if you don't know what to look out for.
Oh, also, although not a cheat. If you're trying to get through the game as quickly as possible, I recommend picking three characters and using them exclusively. Leveling up will be easier and faster, and it will help ease the pain in your bank account (although don't expect not to be broke, you will always be broke no matter what you do).
You may consider leveling up a fourth character, too, just for backup.
I recommend a party of Vaan(versatile, fast, good magic), Basch(best tank), and Penelo(fast, best mage). And Ashe, if you need a fourth (works well as a backup mage).
"Card Mod" learnt from the first GF you acquire, Quezacotl, in FF8, is very broken. You turn enemies into Cards with this ability, and with other abilities you can turn these cards into very high level magic early on in the game.
This is a horrendous explanation. But FF8 is probably the easiest game to cheat without using codes.
