I'm a little unclear on how many players you envision this for. Would you be thinking one monster player and any amount of other players?
As for the points, I would probably tweak them for the monster a little bit. If you assume a base BP of 85 points for each creature, then using the rule of 15 from the book, the creature would gain an additional 15 points for each two opposing models. Uneven pairings would be ignored.
Perhaps a nice addition to the scenario would be an example creature build or two as well. Maybe one for a big, dumb monster and another for a fast and cunning one.
Very nice work though! I've not gone to the trouble of trying to make my own scenario yet. We haven't played enough to warrant it.
It was designed for a 1 vs 1 (someone plays the monster, someone plays their team), think like how Lurkers and Threshold work for Strange Aeons. For a demo or multi player game you could have people divide up the team and play figures if you wanted. If you had 5 players, 4 could divide up a larger group supers and one or two plays the monster(s) (if more than one).
The Points are tough as I tried to keep to the balance guidelines in the book without making the monster a beast...nobody wants to play against the unbeatable opponent and also I am trying to keep in mind the game length from going on and on....which is a huge turn off to players.
The Creature build idea is a good idea, I thought about it but then I felt that I would be railroading the players into templates instead of letting them come up with their own.
I lack the games yet or the tests, I am more of a theorist and writer (which I have done in the past) with LARPS, beta testing rules for various companies and such...
