Just kind of stepping in to say that we should really "creating a wiki for the sake of a wiki" in mind - or in this case, "creating an alliance for the sake of an alliance". Nintendo's something that covers very large ground, but I really don't think people should be throwing around ideas like this so hastily.
NIWA's garden motif comes to mind. A wiki can really only grow when people give it lots of care. But when there's a small audience/group of editors, it becomes much more difficult. I also think that if more alliances were to be created, it'd be created by series fans for the fans. But that's a given, I think.
Also going to add in the fact that Professor Layton's actually a pretty big series right now. A new game's been coming out pretty much every year (since... 2007, I think?), a full-length animated movie that even got officially released in English, and it's pretty popular. I'm a pretty big fan of it, myself, although I wouldn't be able to help out with setting up a wiki since I can hardly focus on WB right now.
I think things like this should be approached less from a business attitude with theories, which is kind of the sense I'm getting right now. Or... uh. Well, bottom line the feeling I'm getting is just 'making stuff for the sake of making stuff', which isn't a very good idea for things like wikis, but unfortunately it happens a lot.
Or maybe the feeling I'm getting is that people who know the company/series well should be the ones plotting/hypothesizing? I can't really tell, but either way it's bothering me a lot.
