The Laughing One
Er, I'm not sure thickness is a fair way to look at it...Weren't most of the 3.0 books SOFTCOVERS which would naturally be less thick than their 3.5 and 4e counterparts.
I'm pretty sure I've seen Echohawk post his table showing that WOTC is basically on the same track as they have always been since they acquired TSR. Basically, 1 book per month.
If that's true, we should see ~24 products (2 years 4E). How come I see ~2.5 times that number of 4E books on my shelf?
More book space means that WotC is getting more money out of the property, either by producing more books, more hardcover books, or thicker books. Sure that softcover 3.0 adventure might be less thick, but that 4E adventure is 2.5 times as expensive ($9.95 vs. $24.95). The same sized adventures are 50% more expensive ($9.95 vs. $14.95) WotC has now moved to publishing very tiny race books. Half of that difference might be due to inflation, the other half on color prints and poster maps?
