It is very possible that any of those things could of happened with Eric but the very second he was introduced the rage and outcry was heard from coast to coast. There was never a chance to actually build on him because the dev panicked and wrote Eric out as soon as possible. I don't even have it in me to have yet another argument about how Eric fking his girlfriend isn't even cucking because the kind of ppl that argue against it are the ones that just want to start the game with every girl already being a complete sex slave with no build up or progression at all. Which makes you wonder why they don't just go flip through 3D porn comics instead of wasting time with all the dialog in a porn "game"Just a few examples if what COULD have happened with Eric to make him worth having...
Teach Max how to dominate and control.
Use Max in a Lisa Training and forcing Mom to watch
Forcing Mom to service her kids
Bringing Bondage and Discipline into the game
Or the ultimate Cuck, Have Max Cuck Eric with his Mother after they find out his secret!
But all he is in this game is a Peek or No Peek choice.
I think Eric was implemented poorly but I also think ppl overreacted to him.
