As someone who has been in the swinger life, this is one of the closest games I have seen to real life. Of course, we are not all as gorgeous IRL. I was never in the game when I was married but got into it after. Who knows, might have saved my marriage if I somehow talked her into it. Have experienced it with girlfriends since then. The way I played this, being honest, tag teamed wifey, did Amber all the way, then the FFM with high confidence, for the most part, is pretty close to how I have done the open relationship thing with my girlfriends.
Kudos to the dev, keep it up.
