I can't believe I'm actually buying this game, but I want to know how it turns out. I am big fan of the Dynasty Warriors and Samurai Warriors series. The game play gets a bit redundant after a while, as it is a hack and slash that involves a lot of button mashing. However, it is fun because of character development, and the overall history that the games are based off of.
Now, this game basically takes both of them, and mashes them together in one universe to combat a fiend named Orochi, who summoned them there for God Knows What (Either to get them to join his army or get some amusement. I have NO idea.) Both Japanese Warriors and Chinese Warriors alike combine forces with strange teams and pairings. You assemble a party of three warriors from either game, and can switch them mid battle. It seems interesting to me, but I think that Koei is pushing their success; Dynasty Warriors and Samurai Warriors basically survives on a large fan base here in the US of A, rather then the general public sales.
This game comes out in the USA in late September.
