Personally, I cannot subscribe that FFG assembles their games worse than other companies. My copies of Twilight Imperium 3rd Ed., Arkham Horror, Doom and Runebound 2nd Ed. have all been complete and without any complaint. But I guess my sample is statistically not extremely significant.
Same with me. My groups bought TONS of FFG games (like 10-12 between me and me buddy) and we've never had a single problem with them. But then again, I'm probably statistically insignificant too.
