Time needed is the real issue for me as well, but it all really depends on how long it takes to upgrade and get new ships. I can't see myself playing this more than a few times each month, because of my classes, and the other games I play (all two of them). It looks like a fun way to kill a half hour, and if I can get some of my other friends onboard then I'll be even happier, but from what I've seen, it really isn't the type of game that demands constant attention.
