Well, it seems that so far we have zero (0) people wanting to mod Mega-Survivor. I think you should just do it, Ang, since it is your brainchild, and all.
As to the Barrow-Downs Survivor, it's quite the idea. I'm not sure I'd really be up for it, though, for much the same reason as Form outlines above. Also, I'm not sure any amount of rep points would be incentive enough for me to comb over davem's posts.
Or... if neither of these seems to get off the ground, maybe Tuor wants to try out his Orc game...?
