Way too lengthy, and there's nothing accomplished in 16 vs 16 chess besides agitation. Having 16 people try and collaborate is a pain (a lot of recent mafia games are having issues with just a group of 4 collaborating successfully) and really there's going to be 1 or 2 people running the whole thing on each side and telling everybody else what to do anyways, so really you're just burdening the rest of the players into paying attention. And if the board is not revealed how in the world do they know where to move? There's a ton of flaws in the idea that it just isn't plausible, I don't see any way to rescue the idea unfortunately. Oh, since I'm posting anyways, I think it'd be a good idea to move this topic and the upcoming changes topic to the subforum.
