As the International Coordinator for Living Force, please allow me to correct a few of your points.
Living Force allowed players to purchase a specific ship one time during one GenCon. Other than that special additional opportunity, ships have always been purchasable whenther or not a player ever goes to a big convention. Players have never been limited or specifically rewarded for being abvlew to travel (heck, even our 'Celebration II'-only module was eventually released to the public specifically because we did not want anyone feeling left out.
As for having different GMs of different skill levels in a Living campaign, how else can we do it? Fly a cadre of GMs all around the world? It would be nice but ultimately not feasible. Besides, 67,000+/- players all over the globe seem to like the tournament play and continuous universes; I suppose we 'amateurs' must be doing something right.
As for the bluff and counterbluff of your example, I really could not say. From your desciption that does sound like a bad GM call but without his side, how could I really know?
If you have any specific critiques about my campaign, please feel free to contact me directly at august@rookhaven.com I believe the gentleman only wanted to know what the RPGA and Living Campaigns were (the latter of which you answered quite well). Anything further, I invite you to adress to me. If there are real problems with Livign Force or anythign within your RPGA experience, I will be happy to help.
