I have a question that may belong in strategy/tips, but I don't think it's big enough for it's own thread, so excuse me if it doesn't belong here... I was thinking of doing a financial playthrough, but I'm not sure if it's worth it. Assuming I just play normally, without micro-managing the bonus yields, about how much extra base commerce do you expect I'd earn (maybe a range, like 5-10%, for example)?
