Seems interesting but I had to dig in deep into their wiki to find what the minimum requirements were.
>At a minimum, you'll need a machine which is capable of running the Doom 3 game on comfortably high settings.
As someone who hasn't played doom 3 this isn't very helpful but at least it's a decent ballpark that tells me I can't run it. I'm just glad I didn't download gigs of data just to know for sure I couldn't play it.
