In this question:
Should I allow a PC's spells to affect a very large space vehicle?
They ask about balance and how it relates to some mechanics from the 5th Edition D&D mod (addon?) Ultramodern 5e, and actually includes additional rules from Esper Genesis (a 3rd party source for space combat).
Is this all properly contained under the 5e tag for the question, or should we also include other tags like ultramodern-5e and esper-genesis?
Or maybe even just dnd-5e-3rdparty (exact verbiage up for debate) to cover everything?
