Thanks for the input so far, and I do appreciate it. I also understand the initial "Dear God, NO!" response.
I'm working up a more in-depth post as to what I propose, because I don't think that "Sleeper RP" is as descriptive as it should be. As Ghost points out, it would be rather complex and long term. It would also involve a lot of secrecy, but in the end I think it could open up a lot of possibilities for RP outside of just "OMGICICLEPEEPZ". My "Nikiruu" character was a sort of dry run for this kind of RP, and one that was far more in the open than what I intend to do moving forward. I also would like this to be far more "interactive" and not one crazy loner's attempt at a "Project Mayhem".
Anyways, please feel free to make suggestions. I believe that if it is done right and with proper concern for the RP community as a whole this is a viable RP direction. While I understand the initial responses, I would like to challenge you to make your case more in-depth. Why do you feel this way? What suggestions do you have for an alternative? If you never knew a character was influenced by "Sleepers", what would your response be if one day you found out that even one action you took was due to their behind-the-scenes machinations?
