The thing about role-playing games is they evolve; they progress through edition after edition, refining their rules sets, or repackaging the same old tat in pretty covers. A new edition is D&D is always controversial. Either it's too different or it's not different enough. Emotions tend to be pretty polarised. Well, they would be, wouldn't they?
