I really hope that's not the only combinations. I'm actually putting effort in choosing what I'd like to read, some ATLA-ish story and my choices are not near thatIt will matter, we just don't really know exactly how yet. Holly can give some advice during her dates with Ian in chapter 3, so we already know what the best combinations for the first two choices will probably be:
Fantasy + Revenge
Sci-Fi + Chosen One
Historical + Call of Duty
