DaCostaBR: I almost shit my pants when I saw this news!
I have it on PS3, but that one is in the bottom of my closet, such is the nature of consoles. Plus, I wanted to play it again last year when I was away from my consoles and I couldn't, and I'm planning to move away again next year, so it's so great to just be able to download and play it on my PC anywhere.
Also, I always thought about how much this game would have benefited from mods. It will have been years since the first release, so I don't know how much support it will get, but I sure hope it does.
P.S.: I never played Dark Arisen and I wouldn't have bought the game again just for that, but combine that with a PC port and I'm definitely going for it.
Dark Arisin adds a whoe new bevy of content. And it includes in easy mode, and a different menu music.
