no real comment as I have rarely ran into ppl who RP (I knew 1 person but they changed servers a bit ago) the idea seams noval, like walking past a street preformer in RL, if u like it u stop & watch/join if not u move on. ERP is an acrynom I did know about till I kinda "had to" (figure out what it ment, not actually do it), personal opinion now... its can be like reading an adult book or playing a 2D game, definetly can get u'r mental gears going, thus giving u "material" for later, but would sujest it not be in open-world as u never know WHO may randomly wander apon it & maybe get offended (like letting u'r kids use u'r PC but forgeting to active the parental settings... try explaining that away later)
