I'm not quite done with it (though I've beaten the game with like 10 characters now) but I've certainly put in enough playtime with Sengoku Basara: Samurai Heroes (technically Sengoku Basara 3, I believe) to have a verdict: it's freaking great if you're into Musou games at all. Totally off the wall story and script, doesn't even pretend to be serious like many of the Musou games do (as serious as the story can be when a single person is murdering several thousand by himself, at any rate). I mean, hell, Tadakatsu Honda is basically a Gundam.

Haven't played a Musou game in quite a while, but I get a jones-ing for them every once in a while and this has certainly hit the spot.
