Have you ever tried or have RP servers in minecraft?

I've tried many times and minecraft can be a good platform for RP, but you have to spend a lot of work

medievial servers with the superguilds are nice for rp

Personally, I've never played on any RP servers, although I wanted (and still want to) create one. I've always liked roleplay, furthermore the various plugins and mods for Minecraft are enough to guarantee potential players a lot of entertainment and a non-linear, rich storyline.
I agree with Alexander VII, making a server like this would indeed take a lot of time and effort, but I'm sure it would pay off in the long run, as such servers are rather rare to find, and they are definitely a lot of fun.

Role play in minecraft? Sounds like something new. Never heard about it before.

yeah i tried, this is ... weird

Well, actually, i already played roleplay and i think it's good but not for a long time, in minecraft you do the turn in something like 2/3 days, after that, it's looping, farm, sell, have fun, farm, sell, have fun...
