We have nominations for both Mass Effect Trilogy and Mass Effect - All Media Types. Nominators, which do you prefer? Do you want Andromeda lumped in or separated out?

We have nominations for both Warhammer 40.000 and Warhammer 40k (Novels) - Various Authors. Are these the same fandom? How do the nominators want this franchise handled?

Worldbuilding tags

Worldbuilding tags cannot be used as plot prompts. Please replace the following:
Worldbuilding: Post-Canon (DS9)
Worldbuilding: Tech lives (SW TBB)

Please be more specific about the worldbuilding or explain to me why this is the best/only way to nominate:
Farscape
Worldbuilding: Childrearing (Farscape) – Childrearing where and of which children? Peacekeepers? Among Chiana's people? Elsewhere? Would you truly be satisfied with anything?
Worldbuilding: Religion (Farscape) – Which religion? A space religion? Christianity in the canon context? Religions plural?

For All Mankind
Worldbuilding: What's happening in China (FAM) – Can you rephrase this? "State of Chinese Space Program" or whatnot? (Sorry if that's not what you're going after; I haven't started s3 yet.)

Jupiter Ascending
Worldbuilding: Childrearing (Jupiter Ascending) – Childrearing where and of which children?
Worldbuilding: Religion (Jupiter Ascending) – Which religion? A fictional space religion? A RL religion in the canon context? Religions plural?

On a Sunbeam
Worldbuilding: Restoration (On a Sunbeam) – Restoration of what? Or is this a game mechanic?

Star Trek: Deep Space Nine

Stargate Atlantis
Worldbuilding: Sentient Atlantis (SGA) – Is this already a thing or a plot prompt?

Other

Star Wars Crossovers
Worldbuilding: Force Hounds (Any Era) – Force Hounds only seem to appear in Dawn of the Jedi, set around 25,793 BBY. Wookieepedia doesn't have any other mentions. Star Wars Crossovers doesn't look like the best place for this, especially as this is a single era thing.
Worldbuilding: Jedi Temple Guardians (Any Era) – Nominator, I would like to remind you that you are being incredibly ambitious and opting in to both Disney Canon and Legends, from before 5000 BBY to 19 BBY for Temple Guardians. I will let this in in ~48 hours even if you don't reply, but I first wanted to warn you just in case.
