There have been many spin-offs of the Dynasty Warriors franchise, set in different time periods, worlds, franchises, etc.

There has been one set in the Trojan Wars (Warriors: Legends of Troy), one set in the Gundam franchise (Dynasty Warriors Gundam), one in the 100 Year war between England and France (Bladestorm: the Hundred Year War), even one set in the One Piece anime (One Piece: Pirate Warriors)!

So, if you could pick a franchise or historical time-period to become a "Warriors" game, which one would it be, and why?
