I do think a choice will come between Benett/Aidan/Clark and maybe Morello storylines because a vast majority of it comes down as forced, and there should be a way to withdraw from it in the future. I definitely think the first "interracial" sex in this series is going to be with Clark, as I don't really see any other character that fits the bill. However with the pace of development (considering this game is a 4-5 year WIP and there's no real sex yet), I think there's going to be years more of buildup till its completed. Probably a 10-year project to see AWAM completed and we're only barely halfway there.
Now, the question is whether people will bother waiting all that time before the dev decides to stop giving them blueballs.
