For example, that's like saying you don't think you'll like the Dark Knight, because you don't like comic books and without ever having watched it. I'm not saying the Dark Knight is a particularly good movie, but it being part of a certain extended universe, having a particular setting, isn't necessarily relevant to whether you'll like it.
In a lot of genre stuff(westerns, scifi, fantasy, etc.), you'll have stories which aren't actually about a fictional future, but about the present or past. Often they'll rework them into science fiction stories, just like how a similar story would have been reworked into a western when those were popular.
For example, Red Dead Redemption could have been turned into a Star Wars game quite easily.
Hell, in the past acclaimed directors like Tarkovski made science fiction movies, so they could fly under the radar with subversive stories, exactly because critics underestimated the story they were telling because it was 'just science fiction'.
TLDR: don't judge a book by its cover.
This being said, I get why you wouldn't bother trying if you disliked much of the Star Wars you have seen.
Having a female character and trying out a variety of cool outfits, dresses and make-up is fun. Especially as most games allow you to do a lot of customisation for female characters. Barbie in Night City, Barbie in Skyrim, Barbie in the post-Apocalypse. I can happily spend far too much time getting their outfit and make-up just right, before I even get down to kicking ass.
Female bad-asses are far more interesting than the boring male action hero stereotype.
Games are escapist fun. I'm a man. I'm tall, I do weight lifting. Why would I play as a man who looks like me, when I can play as a woman, something I would otherwise not get to experience?
