I get tired of having to play as a guy in most games. I read a comment on Guenevere (great wip here) about how it was kinda annoying to be forced to play as a girl which made me realize that not everyone has had to pick a different gender/race/orientation in a game. So for me the option to pick a gender is a relief. Sure sometimes its just pointless fluff but I don’t think removing those options would help.
As for game recommendations, the best stories I’ve found are here but otherwise I’d recommend delight games Paladin, Magium, and maybe playing the free demos/wip so you can get more of a feel for the game. On playstore if you make a purchase I think you can get a refund in a set amount of time. There are horror games on the app store that follow the same formula as well as the lone wolf gamebook (if you can ignore the fact that lone wolves are the weakest wolves).
Otherwise browse around here https://forum.choiceofgames.com/c/off-topic/other-interactive-fiction most free text adventures I’ve seen are, well, not good.
