@SlypheedHeh. Well, if they counted my RP posts AT ALL over on the Minecraft Forums, I think I'd have close to ten thousand. CLOSE, not exactly. I used to play in Freefroam (I guess, they didn't have specific names back then). Plus, almost all of my posts on here are casual posts. Though, I do enjoy some strict Freeroam, and have a few post here and there because of it.
Well, let's see... the biggest RP I'm in now is the first RP I started, which is now reaching the climax... so let's see how many characters there is there.
Jolion, Kassy, Steve, Herobrine(Evil), Herobrine(Trapped/Good), Aaron, Liera, Rob, Liera's Dragon Enemy Dude. So, that's nine characters right there in one RP (Albeit it's been running for... 34 months). That was my second ever RP (Not counting restarting the first RP I joined, which was already taken over by the time I joined). The first RP had about the same... maybe a little less, but I'm not sure exactly. It was Pokemon however, so each Pokemon I had counted as a full character with background and everything. So, I had a lot there.
