I think a lot of people are just buying plex with in game currency and that is how they pay for their subscription. However that turns the game into work and not fun.
It is a great game and I am glad it is still going strong but I doubt I will be back. I much prefer the quick games these days that doesn't require me to invest hours at the time to get anywhere. I am lucky these days if I can sit down to play games for an hour a day without interruptions.
