Because in most action games or platformers, the use of analog movement on the left stick is desirable, and that's one thing keyboards don't do.

Not to mention if the game was originally designed to use an analog stick for fighting or whatever, the transition to mouse might not be the best, ie playing Skate by flicking the mouse in different directions?  Doesn't sound right.

Mice are more accurate, that's not a debate, but you can definitely argue that a gamepad has the best button layout and comfortability.  Especially if the game was originally designed for consoles, not PCs.

8GB?  Uh, it's only 804MB.

i just found out the demo is 10 minutes long, i think i am gonna wait for the full game

804 MB is nothing hehe.

at least this time they seem to be doing it right, and not like that DMC3 SE piece of... port.

I will try it :) 

I just bought DMC3 for my PC the other day (bargain bin

 And to completely test your performance, get the benchmark aswell. Demo download is on the same page so you can get both in one stop. http://www.gamershell.com/news_52200.html

Edit: that fileshack link requires you to register before downloading. That's just really gay, demo downloads should be free.

I'm downloading it right now, it should be done in just over 40mins, i want to see what it looks like on my older Computer compared to the PS3 demo i have.

"Register" and "pay" are not the same thing.  It's a free account, but that's fine I'll add your link instead. 

It just finished installing for me.  Starting it up now.

just played it,yeah its better with a gamepad
