These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.

"Complaining about technical aspects is fine, but sympathizing with one faction because of their technology doesn't make any kind of valid argument on the morals. No matter how cool or otherwise the bad guys are, they're still bad."
