im doing them in order...

I finaly bought it.
Dam story mode has been BOOOOOOOORRIIIIIIIIINGGGGGGG!
Every fight ends in 4 secs.

yeah forgot: after you beat two random destiny oddeseys you have to buy the save replay in the PP catalog >_

The first fights in Story Mode are realy easy because they are designed to be a introduction to the game. Later you have Story mode fights that last some Minutes.

Have fun gaming

@Angelfire

You should do them in order if only if you want to keep it strictly story wise. WoL's story is really hard, and it's only with some Dissidia experience under your belt that you can accomplish it properly, since there are some really tough boss fights in there.

@Simulacrum

Like Stefl said, the early battles in the tutorial are really really easy, just wait until you get to Warrior of Light story properly, or to the more harder story modes like Shade Impulse or Inward Chaos. Also when you get the Duel Colosseum, there will be fights that will take you easily over 5 minutes long ;)
I've posted a few videos a few pages ago (in the 2nd page if you're using the 50 posts per page) if you want to check out fights against Lvl 120 enemies.
Also, there's always Chaos xD

Hmm... does somebody know what "Steinchen" are used for? I don't know what they are called in the english version but it would be something like Stone or Stonlet.

Hummm, do you gain that item on the Duel Colosseum by paying 3 medals? I think in the Eng version it's called peeble. It does absolutely nothing :P It's just for % completion xD

No for 15... I am wondering because they do not pile, so my items menu is full with single "Steinchen" and sometimes there are 2 or 3 on a pile but not more

In which DC are they worth 15? Their price vary in conformity of the difficulty of the DC, but they don't really do anything, or at least I haven't found any use for them, nor do they unlock any new synthesis item. Plus since they don't pile up, I also think that there's no accomplishment to be gained for gathering X amount of them.

in the third DC i think
