I believe they are all the same "size class," at this time at least. I've only started collecting this line with the Super Sentai line (Power Rangers).
This is not my sheet, but I did find this Google sheet when I was trying to find a checklist of what all was available for this line from Bandai - https://docs.google.com/spreadsheets/d/e/2PACX-1vRFaXNlePnBBS9HhTSnG2W6Umn40rv6O4qTmsgU3ctR7QcoinQy2XbbMqWRWIc0SVuusO1qfgiakngm/pubhtml#
Here they have it categorized by the Series, so maybe that would be the best way to approach it.
Oo! This is very helpful! Browsing through that spreadsheet, it looks like categorizing by series/license
would be the best approach.
I see no real advantage of breaking them out between Super Mini-Pla and Shokugan Modeling Project aside from the 'well, technically...' folks. Maybe since they share the same abbreviation just keep it simple as 'SMP'?
If you think enough people will recognize "SMP" as both of those lines, we can do it that way. We could also name the line "Super Mini-Pla/Shokugan Modeling Project". We can always split them up later, too, if enough "well, technically..." folks request it.
Another issue though is there's technically different releases of the same product. Some have been re-released/reissued and some may or may not have candy included, depending on which country it was sold in.
That's not as big an issue as you might think. Each iteration would get a separate product entry in our database. Reissues could get a "(reissue)" in their product name to denote them as such. Releases with candy would also get their own entries separate from the candyless releases.
I'll start making some categories so you can get to entering stuff. One thing to keep in mind: I noticed that spreadsheet includes the MSRP of the toys with sales tax included; we prefer to list the MSRP without sales tax included when possible, since taxes tend to fluctuate more often than prices do.
EDIT:
All the categories have been added and you're ready to go (there are even a couple of items there to get you started). Please let me know if anything needs changing.
