gamemaster 17 million in food! Wow! Since I started stockpiling I have gotten to about 1.5 million. I try to limit how much I use for regular play, so it is growing slowly but surely. During Red Rings I was able to play the first 4 mines twice a day (up to Amythest) but the ruby, topaz and university levels I could only play once per day. Still, I was pleased with my haul.
My current levels are 18,500 per hour daytime ready in about an hour, and 76,497 overnight ready in 8 hours. I am in China, needing one more dragon egg to complete the Fire dragon. Just getting started on metal dragon portion of the region, with a lot of side quests still to do and father quests also. A long way yet from Atlantis.
My lowest regen and generator items vary depending on night or day setup. Lowest in day is green 113 and blue 990. At night lowest green is 136 and lowest blue is 705. Thus, very little on offer in the shop is of value. Even stuff that is unavailable because it is for the next region is already below my lowest level. The developers need to take into account that we play the special events and get slots filled with higher value items. I don't know what the point is of having so much stuff off-limits when it isn't ever going to be worth buying. More care needed with this aspect of the game design.
