there isn't enough vore games that end with you becoming top pred. Most usually have you survive but your tormentors (from ther perspective of them giving the most dead ends) get away scot free. stuff like the Pred End in this game give it a nice push and pull. It's just nice to have the option of being higher on the food chain.
100%, it seems that most of the interactive vore content out there is prey focused, I guess that has something to do with it being easier to make more routes/options since they all dead end. This game has some nice variety even if I'm not a huge fan of the "Vore is common and everyone does it" setting (I mean just look at what's left after the pred ending lol)
