I realize I Have No Name kind of brought this up a while ago, but I want to throw in my opinion on it. I feel like for survival challenges it would make more sense to rank the the people who actually 1cc the game by remaining resources at the end, kind of like the TD special challenge from whenever ago. As it is it really seems to just boil down to a scoring challenge rather than survival, which I feel takes the fun out of it for those who were just playing for survival. Naturally I'm not saying change the rules midway for this one, but I think future challenges would make more sense that way, at least if it's going to be called a "survival challenge."
On a related note, I'm a little sad that nobody else is doing SA Lunatic. I expected there to be some competition going on there.
