I play farm story quite a bit and somewhat disappointed on the fact the only way we can acquire gems is to buy them or finish out trees and/or plants. I have completed all my trees and working on plants. But I think there should be a monthly bonus on gems, just a few every month.....make it a percentage off your level you are on or something where it would make people want to play even more.....that is just a thought but just some incentive would be great. It just seems it is so hard to build them up.
