I think it’s attracted less attention because asexuality is inherently less dramatic and currently dealing with less direct persecution than other non-hetero sexualities. It’s good to see it included though, and treated reasonably well, in that the character is written well enough to convey that they aren’t interested in that sort of thing generally, and it isn’t a merely lack of experience/worldliness, or that they just aren’t interested in the PC that way.
In some ways I feel like The Outer Worlds is a victim of its own subtlety in a lot of the writing. It works for that character, but a lot of the other characters are sort of overcomplicated in a way that makes them less engaging, rather than more. It’s a little more real that way, but that also clashes with the rather exaggerated and silly-feeling setting. I’ve heard people say the story is very black and white, but I think it’s a lot more complicated than that, it’s just that the complicated-ness isn’t working well for it, because of the mismatch between the obvious evil of the corporations and the nuanced characters. I mean, I guess that’s maybe part of the point it’s trying to make, but it doesn’t quite land.
In general I feel like this could be said to be an “issue” with a number of Obsidian games. Because they tend to write these complex and more-realistic characters, yet you only have limited time to spend with them, and mostly it’s in this “I am questioning you” way, rather than in a more filmic way, it’s less inherently engaging than the more trope-y and straightforward approaches other games take. They tried to fix this a bit with Pillars 2, by making more of the character of the companions be revealed in their quests, but I think the end result was that many players just didn’t see a lot of it.
