I have got an answer from MM regarding catastrophic events and homeworlds:
In both (sim and turn-based) a players' HW (or their first HW) is immune from catastrophic events. It was too devastating to have the HW obliterated by an event. The immunity has not been in the early Versions of SEIV.
Well, I can YES this for all of my longterm simultaneous games, but not for turn-based (this seems to be a *cough* bug *cough* in turn-based). Another strong reason to play simultaneous.
Oleg, I recall a problem with AI population distribution under non-simultaneous also, any news on this ?
