I am on the verge of beginning a fresh campaign to introduce some new players to Basic/Expert Dungeons & Dragons, and I am facing a difficult decision: Should I play strictly by the book or should I use my preferred house rules (both my own and some I've discovered in the OSR Web logs of others)? If the former, then I will be exposing them to a "pure" D&D experience. It may be less forgiving and it may make less internal sense due to inconsistencies, but they will understand the game's inherent strengths and weaknesses better. (The lie to this is that, as far as I know, no DM outside of official tournament play has ever run D&D 100% by the book.) If the latter, then their first experience may be smoother and potentially more interesting. If I choose the latter, should I tell them which rules are house rules, or would that distract and/or confuse them? Comments are welcome (as always, but here they are especially appreciated).
