(Sorry in advance for the long post!)
I have been thinking about gems a lot lately.
I read through the entire "What should I buy with my gems" thread. Other than a Living Wood Tree, and maybe a Magic Fruit Tree, I have most of what is recommended (pending updates, of course). I am an upper-30s level player (37? I think) and I have been taking my time with the story line (just starting to build Sabina's house). I know there is a lot in store for me!
However, I hate unfinished things. So the fact that I have a ton of useless half-finished buildings in my inventory drives me up the wall. I am thinking that maybe finishing some of them using gems could be good, considering drops and prettiness and uniqueness.
Some of the buildings I have are quite old (I think my first event on this account was the Vineyard Estate one). Here is a list:
Vineyard Estate
Horse Track
Orphanage
Thankful Mystery Dinner Table
Ivy's Petting Zoo
Glimmer Fountain
Colosseum
Griffin Roost
Festival Grounds
Cherry Hive
I missed some events, so I don't have the base building to upgrade (although I do wish I had them... The Castle Gardens looks SO pretty!)
My question (to start with) is this: which ones would you say are worth upgrading? And does the upgraded Orphanage really only drop coins hourly?
