Looking at the Super Robot Wars Original Generation tag, I wondered whether or not it would make sense to make a tag for the original elements in the SD Gundam G-Generation, both characters and mecha (probably SD Gundam G-Generation Original), and suddenly grew concerned about the entire range of SD Gundam tags.
For those that don't know, SD Gundam is a subfranchise of Gundam which focuses on depicting the mechs in a chibi/deformed fashion. Part of the rise in chibi/deformed art was because of SD properties like SD Gundam, which immediately brings forward a question: if we have chibikemo, why don't we have chibi mecha? You probably see where this is going: SD Gundam is functionally a chibi mecha tag that's exclusive to Gundam, unified by that SD look whilst featuring a smattering of other stuff that's just lumped in because it bares the SD Gundam name (so we have SD Gundam G-Generation which only uses the SD look and doesn't go beyond that, we have SD Gundam Gaiden and SD Sengokuden which make the mobile suits sentient, etc).
Personally speaking, I think it would make sense to get rid of the SD Gundam tag and use it (and SRW) as a base to make a chibi mecha tag, or sd_mecha as it is actually called since searching 'chibi mecha' in Japanese only gives you Chibi Mechagodzilla (speaking of, do we need sd_kaiju/sd_tokusatsu too??), and have the individual SD Gundam tags just directly imply the Gundam series tag. For G-Generation in specific, it seems that there is no - in the title, and unlike Super Robot Wars, the individual game tags don't see much use, so we could probably collapse them all into G Generation and just have a sub-tag for the original characters and mecha.
