It is so hard to come up with remotely serious question titles when you have to talk about zombies, of all things...
The recent question zombie spawning asks about how zombies are spawned in Die2Nite... or however the capitalization goes.
An existing question from a month ago, Does killing zombies reduce their numbers on subsequent days, asks about a specific component of the spawning algorithm. Consequently, it got an answer with the full spawning algorithm.
The newer question is not really a duplicate of the older one, as it is more of the superset. They don't attract the same answers, it's more that someone exceeded the needs of the older question by providing the necessary answer that would satisfy the newer question. So as a result, it feels like it would be backwards to close the newer one as a duplicate of the older one.
In the other direction, it makes some sense. Compared to the existing direction, it's more agreeable that you'd be directed to the full algorithm answer if you ask about a specific portion of it.
Both seem valuable as questions. Thus, I'm thinking a merge seems appropriate here (after some minor title revisions). However, this is in the backwards direction and merges are a lot nastier to revert than if we simply closed it, what do people think about this? ♪
I'm also using this to launchpad merge-request, which people should use if they find a particularly enticing candidate for question merging that they think should be brought up for discussion.
