I didn't know what to do with my obsession beyond compile it into one huge list so that's what I did, okay. As I write this, the host-o-community has at least 217 entries that are clearly FNAF fan games. I realised how big it was when Fazbear and friends usurped Slender Man as the most popular fan game subject on Game Jolt. Every morning I check Game Jolt, and every morning I see several new Five Nights games. My readme file obsession has tailed off in recent months, replaced by a fascination with fan games for Five Nights at Freddy's - a game I've only played for ten minutes in the demo. I know, right? Game Jolt chose to section Five Nights fan games away from the main stream, as they were flooding everything else out, and currently hosts over 4,712 in various stages of completion.
I certainly did start, though, so now I've boshed another 922 games onto this list. At one point, I had hoped to compile a new list of the 2362 games on Game Jolt, but, well, there were 2362 of them. Update, September 14th: Shortly after this post, Five Nights fan games really took off.
