Good for fans, not others.
Why the 2? The gameplay is very shallow, combos might as well not exist since you can just escape them by pressing R2 if you have enough Cosmo. The gmae quickly boils down to "Wait for the opponent to use an special, dodge and use users", since the start up is son long, most aren't useful in combos, just look at Shaka, how is he supposed to combo with his specials?
The character roster is also a bit of a lie, there's not really "50+ saints", y'see, you have 5 Seiyas(v1, v2, v3, Sagitarious, Gold), 4 Shiryus and 4 Hyogas(v1, v2, v3, Libra/Aquarius), 3 Shuns and 3 Ikkis(Their Gold cloths are DLC), you have two Deathmask, 2 Aphrodite, etc, and they play almost exactly the same between each other, so the end result is a reduced cast.
Still, for fans of Seiya, this is probably one of the better games, the rest should keep away.
