I'm sure some people here remember the roleplaying maps from Warcraft 3, including MRP and DoBRP back in the day. I'm currently working on resurrecting that kind of map.
I'm collaborating with several people at http://cortexrp.com/ to create a roleplaying map library that anyone can plug into their terrain and make it into a fully fledged roleplaying map. We're also working on our own roleplaying map to demonstrate the capabilities of it.
I don't have much done quite yet but it's coming along very well. Basic commands such as spawn, remove, kill, scale, are already implemented.
I'd love to hear thoughts and ideas, or even get some help if anyone's willing. :)
