Mistakes were made and the gaming press took advantage!
Lord British points to his Facebook page, which in turn points to a PDF document, where he back peddles about what he really meant when he said what he said.
What he meant was game design is difficult and hard to learn.
What he apparently did NOT mean was that he was the best game designer he ever met, that game designers are, by and large, unqualified for their jobs and “suck,” and that every game designer he has ever worked with has been lazy. Any phrases that might have indicated such were taken out of a context not apparent to you, the reader.
Please do not let the fact that Lord British was made to appear to call most game designers lazy, unqualified scrubs deter you from supporting his Kickstarter project.
