That would probably be because most of their titles, like the Colin McRae/DiRT and Formula 1 series largely appeal to European audiences. Because Americans (stereo)typically can't be bothered by racing if the track isn't oval or straight and/or doesn't involve generous amounts of crashing, rally and Formula 1 simply never took off in the US.Kumagawa Misogi said:I don't know how accurate these numbers are but it doesn't look like codemasters titles are big sellers.

But in Europe the McRae series holds a fair bit of prestige, but of course, you don't become an all time best seller with strong sales in Europe only. But that said, popularity and quality aren't exactly the same thing. Just because no one in the US buys their games doesn't mean they're bad. It just means they don't appeal to American tastes.
