BEWARE when saving after Sugoroku.
I just finished a game of Soguroku while trying to play with two controllers to give me an extra boost of luck. Well after I finished the achievement didnt pop up, but it asked me if I wanted to save, so I chose yes and saved it over my one save i've been using after every single Musou mode. Not only does the achievement not pop up if you use 2 controllers but that save erased EVERYTHING I've done in Musou mode. The whole game is back to it's original state. I completed 7 characters' stories and now I have nothing. This is complete bullshit. I put about 15 hours into it and won't even think twice about doing it again. This has got to be the most frustrated i've ever been over a game.
