I think it would be valuable to starting players to clearly state the amount of resources used by a building. For example a brewery uses 1 wheat and 2 water for each brew. This way it will be far easier to keep track of gaining sufficient resources without running low all the time or having an overflowing warehouse. Also this is a very easy option to apply as it simply means adding some text, perhaps under the text that explains what the building produces, in the case of the brewery, where it states: Produces brew as it seems to be the most logical place.
Thank you for a wonderful game.
