i mean if you pay attention in the game, you find out that you had different mothers and irl people who have dark skinned parents can come out light skinned and vice versa. kind of a problematic and unreasonable takeaway. i say this with kindness, no judgement. like just think about it.
edit: additionally, its not the fault of the game devs if you just gloss over important character details like that stuff, haha. i dunno it just seems like a silly hang up
