The Dynasty Warriors series is my guilty pleasure of gaming. I know that every single iteration is basically the same game with a new coat of paint and a slightly different feature or two, but I can't help but to continue enjoying them. I've played a large number of games in the series (3, 4, 5, Strikeforce, Samurai, Samurai 2, Orochi, Orochi 2, Gundam, Gundam 2) and the only one I can say I didn't enjoy is Strikeforce; the game in the series that does things differently.
I haven't played 7 yet, but I really want to. Even with as much as I enjoy the games and can get my money's worth out of them, I just can't justify spending 60 bucks on it. Once it hits about 30, then I'll probably pick it up and play the hell out of it. Same goes for Gundam 3.
