In this case I share [MENTION=22779]Hussar[/MENTION]'s puzzlement - why was this sales model acceptable for 2nd AD&D, but a moral outrage for 4e? (MM June 2008, MM2 May 2009)?Also, by my memory you really have to think of the first 2-3 MC volumes as the "core" Monster Manual. That was the intent as they were published, and is why, say, basilisks weren't in the first one.
