That seems like an awful lot of effort to go through to crap on a video game. It also doesn’t match his “this had so much potential” style.
That’s not particularly accurate. Star Wars isn’t especially dark, just as an example. Sure it gets darker in some places, but overall its a fairly optimistic story, even though the main protagonist has a bigger body count by the end of the first movie than some countries can pull off. War stories are fertile grounds for darker narratives, but that isn’t all they can be.
Given the quarantine, I highly doubt you do have anything better to do. Having said that, I don’t necessarily expect you to go around and gather all the data, just find somebody else who has done it.
Both are used.
Ultimately, its a video game. The reason you find those categories are because A: its harder to spend time talking about how something works than how something doesn’t work, and B: the story isn’t really the point, so of course they aren’t going to spend much time talking about it compared to the gameplay unless they were legitimately distracted by it in some way, or otherwise put off.
