I'd like to find out too. Sometimes the way the game ends is in such a ridiculous place, it makes you think an update won't take long, but then nothing. I am getting to the point where I will probably only pay for finished games, and there aren't many of those....
Kinda in the same boat. I have subscribed to several games, and 90% of the time the game goes "tits up" (abandoned) . Why would I want to support a game that will never be finished, or I wait months and months for an update.
