The Quests are fun, and I'm GLAD they are optional...because of them I've bought several facilities that I really didn't want...but to finish the Quest. I'm a more than a bit miffed. I've noticed that the Quests want me to spend my real cash to afford more factories for even more for future Quests.
I've also lost count of the real dollars I've spent on this game for things. $100+
Why can't I get a product, Example as a Diamond Vase, from working in my NEIGHBORS Ceramic Factory for the Quests
??????
I refuse to buy more factories just to finish a Quest. I already have more facilities than I care to count.
