in the future, if you click on the 'more information' tab right above the download button and look at the tags, you'll be able to see (as the name suggests) more info about the game. major aspects such as genre, setting, and inclusion of lgbtq characters/story aspects will most often be listed there, and never again will you need to worry about guessing such details on your own.
however, not all of the games featuring the 'lgbtq' tag will feature a majority/entirety of queer characters or story-lines: sometimes it may just be one or two side characters in a game who bring minor but notable representation of the community. but, more often than not, games with tags related to lgbtq topics will be heavily (if not exclusively) populated by non-heterosexual or non-cisgender characters, and the creators will consequently base their plot in queer experiences
