Howdy, guys.
Folks should rate the scenario however they feel. The scale means -5 = hated it, 0 means take it or leave it, +5 = absolutely loved it.
Just a note on the statistics of it, 0 is not the average of scenarios. If the average of scenarios were zero, there would be no point running them, as folks wouldn't care if they ran or not -- equal preference for them to play in it or skip it. Anything on the + side, though, means that they had fun and liked playing in it (with higher number meaning the more they liked it). Anything on the - side means they didn't like it and would have preferred not to play in it (with larger negative number meaning the more they didn't like it).
I don't say this to change anyone's vote -- just to clarify what the numbers mean.
