Building up goods is not difficult. This would be easy to understand if you had a more in depth knowledge of the game. Also, a better understanding on how to achieve said goal (of obtaining enough goods to do everything you wished to do). Clearly, if you are having an issue with goods in AF you have an issue in your village. Whether it be a GB issue or lack of GBs i should say. You should be growing your village in the direction you wish to go. If you need to build up your goods, build good buildings. If that is not enough, then you should probably reevaluate what you are spending your fps on.
Personally i upped my arc to level 90 before i even touched another GB. Having a high level arc allows you to gain more fps. After the arc you build up buildings and gbs oriented towards gaining more fps. The more fps you gain the more you can spend. Then you build a chateau.... you get that up a few levels and you instantly have another current age good making building with every 100fps you spend.
If you are unable to create enough goods to do everything you want in the game clearly you are lacking someplace. It is not difficult to fight as much as you want, build as much as you want, or save as much as you want. You just have to know and understand the proper steps to obtain your goals. I can guarantee there is something you can instantly improve on to better your situation. Yes, AF takes awhile to get through, but if you are doing things efficiently you would only be waiting for that next shipment of promethium to come in to do another tech. Goods should not be an issue, and coins/supplies should not be an issue. You can certainly achieve your goals, but it might take you the time to sit down and reevaluate your play style before you can. Lastly, look to veterans of the game for advice. Look at what the top players in the world are doing for insight. If they are at the top they are obviously doing something right.
