I've just discovered the low-usage suggested-order tag. It has few enough questions to seem unnecessary, and its intended purpose seems too vague to be any useful as a tag. Should we keep it or destroy it?
I am going to say no, this tag is not needed.
My reasoning is that the tag is basically the question itself. Let's do an experiment: If all you know about a question is that it is tagged suggested-order and series-name-here, try to guess what the body of my question could possibly contain. There's really only one answer: "What order should I play the [Series] games in?" (Or, in rare cases, "What order should I play [subset of Series games] in?") It's a meta tag which does not add anything to enrich the question in any way.
Additionally, you can't really be an "expert" on the order in which to play games. Generally speaking, there's usually just one official order for a given series anyway, and it's easy enough to look up.
I created the suggested-order tag thinking it would be a good way to categorize questions. However, after reading Mage Xy’s answer, I’m seeing why I should have used the existing tags for game-series-name.
I borrowed the tag idea from Sci-Fi and Fantasy. After seeing several similar questions on Arqade, I incorrectly assumed that the tag would also be a good fit here. In hindsight, I should have created a meta discussion before making the tag.
Go ahead and burninate the tag. In the future, I’ll use series specific tags like portal-series.
