Can these tags be consolidated? Or is there enough value in differentiating the US and Uk versions?
I think we should use a tag synonym. I assume the differences are very minor. They have a post about this on the StackOverflow Blog. Unfortunately, we need some users with 1,000 reputation before we can get those set up ourselves, but the Stack Exchange team can probably do it for us.
It's a funny one, but no, they shouldn't be consolidated.
I wasn't even aware Cluedo went by a different name in the US - I doubt many other Brits would either.
EDIT: A tag synonym would be a good fix (although it might still cause confusion to some), but the question is, what should be the 'main' name. The original name, or the US name?
