Fapping to CRPGs are OK, so long as either
A) The erotic content is presented as text and not images, since looking at images of women is potentially adulterous. Owlcat games are fine here, but Baldur's Gate 3 is more risky.
B) You pledge to always remain faithful to your CRPG wife. Even if no priest will officiate your marriage to a fictional character, Catholic canon law recognizes the concept of NATURAL marriage.
So long as either of these conditions are met, it can't be sinful.
