Arslan: The Warriors of Legend
So, let me try to line this up correctly: Arslan: The Warriors of Legend is a new Musou-style game (in the vein of Dynasty or Samurai Warriors titles) which is based upon The Heroic Legends of Arslan anime, which in turn is based upon a manga series started in 1990.
Mardan rushes are impressive to utilize; pretty good adaptation (though only if you enjoy the anime already)
No real variation between characters; lack of variety in objectives; story's presentation is half-baked; no real innovation to speak of
