When I joined PC, I was planning to join the RPT. I didn't want to start there right away though, as I didn't have any characters prepared and I wasn't sure if I had the time to commit to it. So I ended up just faffing about in the Playground and the Trivia sections for a while, until I stumbled upon the Underground. I had played mafia (well, we called it Werewolf) on another forum before, but I'd never found another place to play it after I stopped using that forum, so it piqued my interest. I lurked for a couple of games (Battle for Gotham and Mafia of Silly Dragons, I think) before deciding to join AWoIaF, where CB wasn't who I thought he was (and that made me kinda salty, but all of us contain salt, right?) I joined Mafia 102 around that time too, where I won my first game with the help of Nani and SteveTheFish.
My favourite games were Mafia 102 (because I won, of course,) AWoIaF and His Return (despite a lot of people dying to inactivity, I got to be a werewolf in the end so that's ok :3)
If I've learned anything from being in the Underground, it's that I suck at EM and, to some extent, at forum mafia too.
I still haven't joined the RPT. The Underground has captured me and is keeping me here. Send help.
Anyway, happy birthday #ONEderground, and stay fresh.
