But it is true that the PC implementation is simple as not playable. Without Gamepad it really makes no sense to agonize over the keyboard and mouse here! While there are mods, but it's not really worth. You have two options:
1. Xbox gamepad (the lightest)
2. Another Gamepad (may be that you have to use Xpadder here so that Windows thinks you have here an Xbox Gamed)
That's why there is a star less although it is a great game!
Now once you have can you put this game to the test a gamepad. I love it (although sometimes very annoying me the PvP). It is extremely difficult, but it makes the time more and more fun and is then also becoming easier (although it never is really easy!)
So do not forget - Gamepad!
