@Darrk this “Planet Death” one isn’t directly related to the Big Bang idea. The naming for that feature isn’t relevant here.
As with the other idea, we shouldn’t limit our feature design to match names for real-life astronomical events. For a game where wizards use magic to lower exploration costs, realism is secondary to game mechanics.
Besides, we have creative freedom to write up any explanation we want for any galactic event. We can ignore the naming entirely until we’ve got the details hashed out.
@TIF that’s a good point, tbh I hadn’t even considered big families just instantly re-exploring. You’re right though, system death wouldn’t be quite right either.
What we could do is include in the event a galaxy status where explorations temporarily risk failure if you try to explore in systems where your family already exists. We could explain it away as a supernatural phenomenon related to the deaths of all the previous inhabitants whose spirits resist repopulation by the same family.
So during the galactic event, it’d be better strategy for everybody to increase their spread than to try to reclaim their losses.
