Is pc version supports xbox 360 or some else gamepad?I has't xbox, but i think game is more awesome with gamepad.And gameplay videos gameplay looks too easy...it was easy, or real challenges comes later?

Yes, you can use your gamepad on PC.

 

In the case of gameplay videos the player charachter was made all powerful in the first video and the second video is just the tutorial. Multiple previews mentioned that combat got harder and they were only allowed to play an hour.

 

So, yes. Combat gets harder.
