It see this happen a lot. The 'settling in' period of an RP that doesn't actually have any structure because its basically a waiting period for the proper story-line is where 90% of people, generally including the GM's lose interest. I think if the RP started with the main story line this would have at least gotten a little further. As they were working out the finer details though I can tell they just said 'lets throw some random missions for them to do for a while' and that's what killed it. I don't blame anyone, including the GM's for losing interest and it is sad to see this go, especially since I liked making my character. I'm not really interested personally in a revival though.
