For me, a non-canon Walking Dead Universe RP called [i]Northwards[/i] was by far the best. It ran for perhaps three years, originally on the old site, and with maybe three different installations and one revival. I joined about six months or a year into it and, over the course of the rest of it I had written 50,000 words for just that one roleplay. And it was a Casual roleplay, not Advanced. Needless to say, that storyline held (indeed, still holds) a special place in my heart. I Co-GMed for a few months during the 2nd Installation, but the creator and GM (I haven't seen her since the death of the old site) is the primary reason why it became so great, along with a great group of RPers with a stellar cast of characters.
