I believe it can catch on within the coming months and improve the ratio vs PoE. Word of mouth and news about FreeLC can do good. Unfortunately word of mouth right now says "pretty but easy". You don't want to be that girl.
Stop slutshaming you shitlord you, it'd be a lot of fun to be that girl
I think the people who care about difficulty already know about Deadfire and either bought it, are waiting for it to get patched into shape, or decided that there's too much gay in it for their repressed homosexuality. Everybody else will be thrilled about the pretty scenery, the romance, and the cute furry animals, and that interest may well keep sales going later.
But for sure this
deserves to sell better than P1.
