I will probably leave and come back a few times, regardless of a wipe. I foolishly bought in for 12 months but I think I've gotten at least 40 hours of play out of it -- comparable to what I would get from a "AAA" game at that price point.
My impression of the game is that it seems really neat early on, and getting into space the first time is really cool. Once the novelty wears off though, the digging and industry becomes a chore. I'm sure that being able to devote time to participating in an org would help but I usually can only pop on and switch some industry around.
I'm also disappointed that the PvP primarily seems to be "crime simulator" instead of fighting.
