I hate it when games don't have any writing or background to them whatsoever. I'm not even going to exclude far-fetched fan theories here, as those at least give some context to what you're doing.
i also like reading weird explanations for things devs dont fully explain, i.e. pokeballs
That being said, it's also not great when the writing is flat and devoid of all emotion. If you're going to give us some writing, put some depth into it so us fans can extrapolate the clues into somewhat-outlandish theories
i.e. ftl's rebellion being justified by your actions, black mesa's competition with aperture science
