I've seen several people arguing over the rules on here and a common idea I see is that people who don't like a new rule point to 1st edition and how it works "better" there while people who like a rule say something along the lines of "this is a new edition, there is no point in comparing it to the previous one".
So, when you think of a new edition of something being released, what do you expect that to mean? And where do you draw the line between "new edition" and "new game"?
The reason I stick with a system is because I enjoy how it works, and if I wanted something radically different I would just move to a different game in the same genre. As such in my mind when you sell something as the Xth edition, what you are telling me is it is the same game I already like, but with bugs fixed and a few additions that hadn't been considered during the creation of a previous edition.
