Well the regular build server isnt so popular, its filled with mingebags too,
And many people that i met at RP servers told me that if RND will open a RP server it will be awsome and i myself will play on it almost everyday,
Ppl want a RND RP server cause they know the admins are good and they not abuse, they are nice and freindly, etc, and thats what most RP servers dont have, and if they do have then they do the RP gameplay shitty (like making doors cost more, make props cost and more)
If you will open a RP server, im sure it will become very popular in no time =D
