Hello all, I understand that the 'Gem mine' is ment to be a long term investment, and I appreciate the thought put into it. Rewarding players that put plenty of time into your game, but I must inquire about the amount of time it takes to get your gems back, or even make a profit off your hard earned (or bought) gems. Perhaps decreasing the amount of days it takes to collect the amount you put in? Perhaps to somewhere between 50-80 days? Or maybe just increase the amount you can receive per day? We could even add boosters that allow you to collect gems faster, or an event where the gem mine can be sent into "Overdrive". 

Best wishes ~ MykelTheMan
