UPS came through with my delivery today despite it coming a flood. I'm about an hour in and I'm really loving it: it's XC2 but better in just about every way. Combat is more involved [since you can switch between Driver and Blade, and between different Blades, on the fly], graphics are really really good, music is wonderful, the "world caught up in war" story feels like it's quicker to get started, and the characters are more interesting [in part because they're older]. Dunno about the total length of the game, but even if it's only about 20 hours that would work out fine with me.
Pretty much a no-brainer if you loved XC2, or thought XC2 was okay but could have better.
