The Unsung War was really good, plot was excellent in it and the FMV's sure beat the static images in AC 4, of course the story telling method was different.
Of course I did like the Live action interveiws from AC Zero, not to mention the Flameco influenced musical style, particularly in the Avalon Dam battle with the Morgan.
Ps. Ace 6 review coming up soon. Hint: Is niiiiiiice, is Veeeeeery niiiiiice!
