Ingame, I'm totally with Circe on this one. Can't do much of programming but I can imagine how many "ifs" and "elses" and variables and gods know what else would it require to work and I'm not even sure if it even was possible to make it work. Probably too many conflicts in the algorithm.
@Whispers: Well, your thoughts are idealistic, and as any idealistic thoughts, they are destined to doom solely by one factor: the reality.
@Kittie: Actually, you have only 2 accessory slots.
And IRL, I'm not fan of polygamy either. As mahawirasd said, in virtually every case (exception percentage is negligibly low) I don't believe the feelings would be equally shared/distributed, there'd be favoritism which would lead to wife-husband and wife-wife (or husband-wife and husband-husband) conflicts.
(not to mention that the whole thing must be ridiculously financially expensive
)
And I don't like sharing.
