I've banished the Furcation Game to a Better Place; and think that they may be some scope at some point for a Lite version in which mash-ups of classic genres are played for a few rounds and continuously mutated, morphed, juxtaposed and hybridised but without the need to write a whole Shakespearian play cum Wagnerian opera every move. This could also be the proper place for hybrids of the type described above, rather than taking up a game slot to itself.
I would also propose killing the Long Game (on the grounds that, no, there doesn't "have to be one of these", does there?); the ordinary Limericks (but keep the multilines; or merge the two into a freeform jazz version); possibly the cheddars (except I like the concept of a game you can contribute really easily to).
I should say that this place takes almost zero maintenance effort from me nowadays, keeping the machine its hosted on up and running and un-hacked-into notwithstanding, so it's no effort to keep it up and running. But I would like to feel more minded to contribute.
All that said, I suppose I can't really complain about lack of originality given that the site itself is basically a knock-off of Dan's and Dunx's respective endeavors in the first place. I could add some features (like unplayed games automatically expiring, or maybe a death vote system) to encourage a faster turnover but I'm not sure how they would work.
