This question about "Dawn of Discovery" was retagged to also contain the "Anno 1404" tag. They refer to the same game, called Anno 1404 everywhere but the US, where it is called Dawn of Discovery.
I think the Anno 1404 tag is helpful as many people only know the game by its original name. But we now have two tags that refer to exactly the same game, which is probably not ideal.
How should we proceed in such cases?
