Xelloss said: I would guess that given the nature of the publisher, NPD undertracks on more niche titles. They probably hit things like MW2 pretty well. The institutional investors who use NPD dont care if Demon Souls sold 200k or 300k, they just need to know within reason who are making the big money printing hits and who isnt. |
I'd actually guess they tend to be more off on more mainstream games. Their coverage of outlets that tend to cater to niche games is pretty good, it's the more casual and mainstream sellers (Wal-mart famously) where they have to extrapolate are where they're more likely to error imo.
