So I was thinking of doing this but it might require a kickstarter to do it.
So go up and rent a seven rooms at a hotel near FFG for about 2 weeks. For those 2 weeks 6 players and one GM run the entirety of the Adventures released by FFG to that date. At the time it would be at least 2 adventure books as well as the EotE Beginner Box with the expansion add on and any of the free RPG and Gamemaster kit games nad any expansions for those as well. The players would design 3 characters (one from each system) and then when time to start they will pick one and the game will begin with the other two as back up if said main is abandoned by the player or killed in game. The games will only be 4 hours in length per session with an 8 hour break. The characters will be allowed to branch out into any direction of the three system thorough out the game. After the game is complete (which would also be recorded) the gm and players will be allowed to go to FFG to have their characters signed off on to continue play. This would happen every year with a different group as time goes one with a different way of doing it (so perhaps no beginner games but only the adventures themselves or only one system allowed) until the pulls the plug.
As I said a crazy idea huh?
