Well I had rated a 4 but dropped it to a 3 for now. Too many bugs (most of which I can deal with) but just got screwed by having a -25 morale penalty for failing a survivor request I never got asked to do in the first place. So much a waste of time now.
I do feel that there needs to be an increase in the obtaining cards department also. I also think that the stacking of the ring of curses ability is overpowered. I think it should do its effect, but not stack repeatedly just restart the timer on the effect.
