Is anyone super powerfull in FF XIII-2 and have powered up all the monsters and if so are you basically invinciable to everything in the game or are some of the enemies still a challenge?
Also i heard it's only 30 hours long but maybe if you power up it would be alot longer and would the end boss be a push over ever.
Like... in every other Final Fantasy? d: Normal Endgame-Levels tend to be something between 40 and 50 in most Squregames. Powerleveling will always leave you with a ridiculously easy final boss fight, but if you prefer that: Go, get it.
Note: You might NEED max level for optional bosses. Those are never as easy as the storybosses.
Just don't use Knights of the Round on Ruby and you can kill it rather easily. Emerald is a bit of a matter of luck, but with the right technique (aka, way too powerful materia combined with level 99-party) it's beatable too.
Malboro can still kill you at level 99, slowly torturing your party to death with stat changes. And they are not even boss monsters.
