i'm not planning on leaving, but i may cut back teams if the game requires more time and attention than it does at present. it seems like this is probably the most common opinion i'm seeing out there. this will be fine for the game overall but only if they MARKET THE GAME to increase the userbase! but if they aren't planning on actually marketing it, it'll really be a problem around here with empty worlds.
that said, if the game pauses for more than a month or whatever, there IS a chance i will just fall out of my HD routine (ie, checking the game in the morning, lunch break at work, etc) and get used to doing other things at those times, and my interest will fizzle out.
