Overall, the rules worked very well, and people grasped them quickly. One nice thing is that I could quickly add on alternative resolution systems- for example, in the arm wrestling contest, instead of a normal opposed roll, I had both contestants roll three times, and added up the totals.

I also used a "stat+3" resistance value instead of the "stat+4" you recommended. In this case, it seemed to work well, since thee were still plenty of people rolling low.

I had a few problems simply from my implementation- I tended to stat people a little high, and some of the characters, such as He-Man, She-Ra and Megatron had stacked abilities that turned them into monsters as far as physical stats went. Some characters like Jerica/Jem and Cobra Commander were equally as monstrous when came to social stats.

We had a few interesting new unique abilities: Brainy Smurf had "Smurf in the Machine" which let him reprogram nearly anything. I was surprised at how quickly that resulted in Megatron being released from his gun form. Also, Pizaz had a unique trait called "Don't Give a Damn 'bout my Bad Reputation", which allowed her to automatically succeed on a social test, at the cost of failing on her next test.

Overall, I'm enthusiastic about the system, and would like to use it in the next LARP I work on. Since that looks to be a much lower-powered one, it'll be interesting to see how it works out.

I'll also be sending you a copy of the modifications I did to the abilities- which wasn't much.
