The only problem I have with Inferno, is that there is TOO little of it. So, by all means, adding to it, will deffinitely be GOOD!
My only gripe, if any, is try NOT to stray too far away from the actual story. Stay within limits, if you can, and if it isn't too bad for the story you have in mind.
Having read the bios, well this is a mod's mod I am REALLY waiting for.!
