Joan does make a fair point that the amount of supplies needed for events, particularly during the Colonial Era, far exceeds the daily output of those in that era. I also had a similar experience during that time until the first time I completed GE 4 and got a terrace farm, greatly easing the supply burden because I could produce around 10k supplies every hour. In the Colonial Era, with those ages' supply buildings, a request for around 80-100k supplies took me a couple days to complete, but the Colonial Age was the last time I didn't finish an event. It became easier as I placed Industrial Age supply buildings and I acquired a number of mini wishing wells, and in the Modern Era now, supply quests are a joke. So it does become easier, Joan. You are at the point in the game where you are experiencing growing pains. I also like to progress at a moderate pace through the tech tree, having played less than ten months. I find camping an era for years mundane, and my first instinct was the desire to criticize players for not advancing, but I realized that we all have different goals and styles of play. For example, until the Colonial Age, one of my goals was getting the four star plundering badge, while there are those who disapprove of plundering altogether. But all those stolen supplies and goods certainly helped with advancing more quickly. Playing on mobile also helps, as I can quickly open the game throughout the day and usually set supply productions for every four hours on days when I am working. I usually try to keep supplies on reserve and a couple of expansion spaces open before an event. So some building quests can be completed quickly. And keep any finish supply production items you get from events in your inventory for whenever they ask you for 24 hour productions, as in 'finish one of each production option'. Reading previous comments, I can see I am slower than some to complete quests, 3-5 per day, but it is enough to finish the events. I have a level 9 World Fair, and I am waiting for the next daily quest, so it's just during the earlier eras when you struggle with supplies, and in the Modern Era, gathering goods for the tech tree will be what slows your advancement to other ages. It's true that having a good strategy in advance is necessary towards finishing an event, but also I agree that the amount of supplies requested in earlier ages is excessive.
