Before I update....

So I've finally been able to get 10,000 goo and complete that set of prizes. Now a mission comes up that says to collect 2,000 more goo... Is it worth it?

Totally worth it, but it's questionable whether you'll be able to get that much goo in a short time, especially if a lot of your neighbors already have the update, as you won't be able to visit them. It probably won't take long before you have to update in order to keep playing, so it may well be a waste of time to attempt that much goo collection. If there was still a day to go, I'd advise full steam ahead, but as there isn't I'd advise not worrying about it.
