After careful consideration, I've decided not to move forward with running this particular group RP at this time. A number of other RL issues and concerns are taking up the majority of my free time at this time, and I wouldn't be able to give this new RP the attention it deserves at its inception to potentially make it as good as it could be.
However, I'm placing this "on hold" for now - should things clear up, I'll reopen this interest thread, and contact those who've expressed interest to let them know.
My thanks to everyone who's expressed interest in this RP, and my sincerest apologies for disappointing you all. Some great character ideas were discussed here, and I hope that they can all be used someday.
As has been mentioned elsewhere in this thread, though, "Game of Thrones" is quite popular - I'm sure that other experienced and extremely capable GMs will choose to run a RP for it at some point.
I'm locking this thread down now, until such time that I have more time and can restart it. If anyone has any questions or concerns, please feel free to PM me.
