For those wanting a little bit of a more serious video about the game:
https://www.youtube.com/watch?v=IBb2BIVrV7MTotalBiscuit's "WTF is", which, for those unknown with TB's videos, is a first impressions video with some pretty good information about performance, gameplay and graphical fidelity.
EDIT:
To reinforce the video, my opinion on the issues stated in the video.
I have played an hour or two so far and i like how it goes so far.
The first thing i noticed was the really high sensitivity of the mouse in the main menu and then when i got actually in-game, the sensitivity was going haywire again.
Very incosistent mouse sensitivity across the menus and other things, not good.
All my graphical settings are on high with the exception of things like Ambient Occlusion which i put up a bit.
The framerate is quite choppy so i will probably have to lower some settings sadly.
My setup isn't that bad and as said in the video, even with dual titans or whatever it is TB has, the framerate is not that good.
Gameplay wise so far, it is nice, i am still in the beginning part of the game really so i cannot really tell too much from experience, but so far it is okay.
I am concerned about the amount of skills you can unlock though really, there aren't that many, but it is more about how you use them.
But yeah, pretty good, though i really really hope to see an optimization patch rather sooner then later.
