We kept it so on vanilla path, it is just swinging, as a couple. The only exception to this is the neighbors key party game, and that is still considered as a couple, as it is part of the game Vicki set up. And even then, Mary does get a little upset if not on hotwife path, but she agreed to play the game, so she doesn't consider it cheating.
Charlotte fits more in the hotwife/hothusband path, as it is letting Fred play outside of the couples thing.
And no, I haven't played those games. I haven't played any games really in about 3 and half years.
