So this is the list I compiled, if I missed one Let me know. I'll update this real time to see if anyone ever cracks the list. 
From what the data shows around 2 years ago was the "Golden Age" for Sci-Fi and NRPs in general. If anyone who was around than can help me with that let me know.

All of these NRPs have a chance to break the top 10 list, I won't update the post count that often but I will continue to make these archived as more NRPs rise.
