1 player games?

Anyone want to rec me some games? They need to be playable by one person, using a phone or a PC without a controller. I'd prefer science fiction, fantasy, or horror* with a strong story component and not much need for hand-eye coordination or the ability to push a zillion keys in an exact sequence in half a second. And I'd rather pay for the game up front than have to make in-game purchases in order to play successfully.

(*For horror games, please not too gory* and not rape-y at all.)

(ETA: On reflection, "gory" was probably the wrong word. I'm fine with moderate violence [think action movies] and blood, so long as violence isn't the main point of the game. What I'd like to avoid is graphic [think horror movies] violence, and disgusting stuff like zombies.)

Thanks!!
