If you don't care about story (and 7's story is genuinely good, not just good for a Dynasty Warriors game) you might want to get Warriors Orochi 3 instead, though. Has a hell of a lot more playable characters, and I liked the gameplay a little bit more. You're also a lot less limited in terms of which characters you play as in story mode.
