if you abort a side quest in forge of empires does it abort the whole quest line

Shortly into bronze age you pick up a second. When you first start the game you just have one.

The game has up to 3 quest slots in the 'Story' tab at any given point in time. Intertwined with the great building is the game's recurring quest system, so I should take some time to explain that first. When should you build it? How high should you take it? 'It's complicated'. Pretty much every top player has one, but it's relied on to different extents. More often than not it's the special event quest lines that mess up plans as they aren't abort-able quests and they often include a 'research a tech' quest.This building is one of the great 'not-so-secrets' of longtime players. As you mentioned by the time you complete such quests 2k coins won't mean much and in the mean time you can complete other side quests that are good for you and get the rewards from them. It'll be better for you in the long run to just keep rejecting those you don't want rather than trying to complete them all and ending up doing things you don't want that will set your plans back. Just keep in mind that the side quests are really just there as an optional goal, something that might align with your plans and give you a slight reward on the way or something that might not align and take you off course (A good example is when 1 of your advisers asks you to build goods buildings that you don't have boosts for). I'm pretty sure that for the lower ages at least 1 of the repeat quests is to research the (or any) first tech of the next age, that one will have to be repeatedly aborted in order for you to keep getting quests while not progressing to the next age. Any quests lines that lead to diamonds or anything really special shouldn't start till you're in the respective age for the quest requirements. Those same quests are also not 'important' ones so by skipping them (and not getting them back later) you're not losing much, 2k coins isn't much of a reward considering the cost of building those 4 houses.

There are a few quests in each age that require you to progress to the next one and it's those ones that you'll have to skip if you want to stay in the same age and get the repeat quests for it.
