There were several pictures of Urotsuki posted in the thread; the first post had a photo of a cowboy on it; there was a lot of discussion over the games, such as whether or not Yume 2kki and .flow were good or whether Yume 2kki was good at being "dreamy", I recall some criticisms about the game Me, and a little over some of the behavior of the creator of Broken Bottles (Doodle, was it?). It all made for a very interesting read, in fact. It's a shame the thread disappeared.
The last time I remember viewing/visiting the thread was perhaps a month or months ago. A while, anyway. That's probably not a good thing. I do know that the thread was never affected by that rogue mod deleting posts a long while back – though, I'm not sure if the thread had been created yet by then.
Specific phrases… the only things coming to me are the names of some of the tiers: "god tier", "meh tier", "shit tier". I can't remember the other ones. Maybe searching for "finished fangames" and "unfinished fangames", though given the thread is /fg/, those might not be good ones.
That's all I can dredge up right now. If I have any spontaneous bursts of recollection about this topic I'll post them.
