Earlier this year, Settlers of Catan was rebranded so that the name of the game is simply Catan. The expansions were similarly rebranded. For instance, Seafarers of Catan is now called Catan: Seafarers.
We have the tag settlers-of-catan, which is what all questions related to the game are tagged as. At one point, we had a the tag catan that was describing questions for the entire franchise, but that was removed per a meta discussion.
I would like to suggest that we change the tag name to catan, but leave settlers-of-catan as a tag synonym. This way, the tag we have reflects the current name of the game, but there will still be a way for those who are not aware of the name change to find questions for the game. The expansions would be similarly changed: seafarers-of-catan would become catan-seafarers, but with the old name as a tag synonym.
I do not have permissions to make these changes myself, but even if I did, I figured it would be good to bring this up on meta since it is one of the most popular games.
