user27906: Yu-Gi-Oh! is a media franchise primarily consisting of manga and anime (along with a trading card game). Over the last 20+ years, it's spawned seven different anime series (two of which are different adaptations of the same manga series). 
Naturally, this site has the tag yu-gi-oh, but it seems to cover all 7 series. Looking at them, they are about:

Original series: 19
GX: 2
5D's: 2
VRAINS: 1
Original series and GX: 1
Original series and Zexal: 1
Arc-V and VRAINS: 1
Kazuki Takahashi (series creator): 2
Franchise as a whole/Unspecified: 4

Some of them are about the manga specifically, others are about the anime specifically, and some of them are open to answers for either.
What is the best way to tag these? Do we just want a tag for each series (covering both the manga and anime) along with yu-gi-oh-series and call it a day? Or does another tagging system make sense?
It's time to t-t-t-t-t-t-t-tag!

user63: Due to the current lack of popularity with the series. It's no necessary a priority, but breaking up the series into tags would be helpful as they are pretty distinct from one another.
GX, 5D's, Zexals, Arc-V, V-Rains, etc. are distinctly spin-offs (Like Railgun is to Index) of the original series (even if they share the same universe and timeline) and should not be grouped with the "original" series.
Ideally we can do something like this:
yu-gi-oh-series General franchise tag
yu-gi-oh-manga Inclusive of the original manga and the R series (even if it's canonicity is in question)
yu-gi-oh-movies All the movies including the 1999 Toei movie.
yu-gi-oh-novels For the novel stuff that didn't really come out here (not a big thing compared to Japan).
yu-gi-oh the "original" anime series including the 1998 Toei series, Duel Monsters series by Gallop (including the Capsule Monsters part that was not released in Japan).
Spinoff series such as yu-gi-oh-gx, yu-gi-oh-5ds, yu-gi-oh-zexals, yu-gi-oh-arc-v,yu-gi-oh-v-rains, should be tagged as appropriate, and future titles should use the [yu-gi-oh + series-name + ] as applicable within the bounds of the maximum length and formatting of SE tags. 
Avoid redundant tagging where applicable. If you want to compare the original series and a spin off , jus use the two series tags sand don't include the franchise tags unless it's there is some relation of the entire franchise itself, like "Why is the canonicity of Yu-Gi-Oh! R disputed, despite being being set in the same universe and supervised by the original series creator?" would have yu-gi-oh-manga and yu-gi-oh-series. Maybe a tag for the creator himself. No need to use the yu-gi-oh tag.
