If people want it it ok but I refused the offer to beta test Second Life as well when it came out as that online stuff is not my line. Wasn't some sexy type online Sim type game brought out as well at that time?
How would an online game manage the language differences between participants? You also might be allocated a server away from your online friends in the forums because of location. Maybe we could all learn Esperanto?
SimCity5 failed because the servers crashed at the start and because of the format so EA would have to make sure they have the capacity this time for possibly, several million Simmers starting at the same time and make the format attractive to those buyers.

There is scope for something like this in the future but I would see it as an over eighteen rated experience (not game) which a lot of older simmers want too but is EA/Maxis the one to make it?
