I was an active user at early beta phase and I was seeing the site turning more restrictive (winding the rope around his neck). BCG wouldn't took off in that way. Probably all these proposals except video games, should be merged on BCG. Ex. on Poker it'a llowed to talk about celebrities/professional players. Ok, BCG should allow it either. BCG is too restrict and forces new proposals to be created. None of them will take off. BCG could be stringer with these topics.
I can say less for WC and EXE merging with Gaming, but I would expect an improvement to gaming and a viable site to these 2 games.
I play a great variety of tabletop and card games, including Poker, Bridge and Chess. I could play WarGames, if fact I hope I can play someday, and many people like me probably likes Magic: The Gathering and variations.
I don't wanna to sign in 6, 8, 10 sites to ask my doubts.
I read arguments to keep these sites separated but I can't buy them. If it is only a matter of my decision I would be merging them now.
EDIT: I would add: Tabletop Game Design, Game Studies and even Games for education and Game Theory to the discussion.
BCG is not going well but these proposals could helps. Actualy question about game design was on BCG definition. Niche proposals need to be less strict about the topics or they won't survive well.
EDIT 2: Maybe Puzzling could be consider for merging too.
EDIT 3: Bridge proposal has no recent activity. It's dead.
