Eric already fucked Max's Mom. That is NTR, are you stupid or just pretending? Genre mean nothing, players define what kind of game they are playing.Please show where in the game description of supported genres does it mention NTR!
It doesn't!
So your complaint about NTR not being in an INCEST game is about as dumb as complaining to a Restaurant for not serving you a Vegetarian version of the Surf and Turf you ordered!
Edit: Don't you think that if he didn't received that much backslash there would be a NTR tag on there? DS can add whatever the fuck he want on that list as the game went on
