Just finished the demo with both characters. I had and still have a hard time to get into the controls. It's totally different than other games of that type that I've played (which isn't a lot... Diablo 1+2, Sacred and Torchlight). The graphic is pretty good and the game runs super smooth, feels polished.
I am a bit surprised about the pc port though... The interface is very consolish and there isn't even any way to configure the keys and such. The first time I've started up the game, I was hammering the I and C key to open up my inventory and character screen, but nothing happened. As there was nowhere a keylayout to be found in the game, I was pressing all keys one by one until I've found what I have been searching... That definitive needs some more love.
To the characters... That sword-dude really isn't my type of character. The woman felt much better, though possible that her hoover-style and flaming hair looked just much better.
I think I like the way the skill system and the abilities work. Would need to get used to it first, which mainly plays into the general controls once again... Needs to be learned first. What I also liked is the dialog and text stuff on bookshelves and such. That gave some background information and was nice to read.
So... I really don't know if I should buy the game or not. I honestly don't know if I could ever play it very long in singleplayer. If at all, coop would be my only way, because else such type of games can bore me very fast (didn't even finished Torchlight. After I've entered the second town, I just stopped playing, even though the game wasn't that bad). But as I am at work most time of a day, it can become hard to find friends to play with...
In any case, I'll guess I would only play that woman with the guns. :>
/Edit: I've voted "Good, but needs some tweaking." while "tweaking" being the interface stuff on the pc version.
