My carrier has a 16M weekly cost.
If I don't play for 6 months it effectively costs me almost half a billion credits. That's not trivial. And to
@Agony_Aunt point, that's a fair amount to recover for a player retutning from a break.
Yes I could suspend some services. But I can't count on doing that. I often don't plan gaming breaks... I just stop playing for a while.
I considered upkeep cost part of the carrier purchase cost. Whether I scrounge the money now or later, whats the difference? So I included 4 years of upkeep cost in my original fund raising. With casual playing and the credits I gain from activities and lots of breaks that should cover me until I'm dead.
