Explaining the 20 hours:
There are two characters taking each about 6-7 hours on a playthorugh. You are awarded 2 different xp points to buy new swords, on my first gril playthrough it wasn't nearly possible to get 50% of the swords for her. To get the final swards you need to play both stories.
The gameplay had some very short backtracking issues and the combat mechanics could use some more buttons (it's all the way 1 button to do almost everything), but the swordswapping, item using and special sword technique using can mix things up.
Comparing this game to MadWorld, i have to say MadWorld had more intense action moments and motion controlls, but had some let downs from time to time. Now Murasama was constantly delivering good quality fun without these letdowns. So for me they are equal, althaugh Murasama has more value.
