My question to other GM's here is, what have you found to be the most relevant things to ask for in an RTJ that speak to a player's likelihood to stay, contribute, write well, be engaged, etc.
I've actually had good luck, thus far, with people who tell me up front that they don't ghost games - but if you
ask for them to say that, it's meaningless, because what else are they gonna say? "I regularly ghost games"?
I would say the biggest thing for me is if I'm with them in other games
or they run a game of their own. Both things tend to reduce the likelihood of ghosting (but not eliminate it entirely). However, in the case of the former, there's a happy medium - one or two games is best, because anything more, and they might conceivably be overwhelmed with the number of games they're in and begin ghosting.
Lissa, it is true that a player who puts a lot of effort into the character concept may stick around - but they may just be really excited about character creation. Same deal with a player who writes a lot.
Ultimately, I feel like it's often a craps shoot. :/
(That said, if you can push the RTJ process long enough, some people will end up showing their true colors during the RTJ process itself - that will help eliminate those most likely to ghost quickly.)
