I've been trying to get the same RP going for over a year now. I haven't had more than one person at a time express interest. That one person, then, just never responds back. 

I'm committed, though. I'll keep trying until I get at least 2 people to show interest and follow through with, at least, starting it. 

I'm of the understanding that people simply don't stumble over it and that it's mechanics are very different from the fandom. I think this is one of the reasons, but I think there are plenty of people out there that would be interested in it if they saw it.

How long have you waited for an RP to catch on? Do you believe there is a time when you should give up?
