Erik is largely correct that casual players are the exact people who do not have brand loyalty to anyone, including Nintendo. The whole idea of being a "casual" is that they don't play many games and aren't obsessively aware of who is making what. Most do not look at the publisher's name on a box, and in my experience as a retail employee, even if they SEE a logo, they don't necessarily know that means who published it. Why would they? That could just mean a licensee or something. "Who published this game" isn't something these people even consider.
As a similar example, I'll assume most of you aren't music enthusiasts. Listeners, sure, but not enthusiasts. Do you know who published your favorite albums? Don't look; just tell me. Was it Starshine? How about AMSI? How about Global Music? What's that, you don't know? How could you be so stupidly ignorant of a product you enjoy?
Nintendo does not have magic dust. People do not buy their products "just because." When speaking of casual users most especially, the reason a product will sell is because they want it, not because of brand recognition or loyalty. Why would someone with little interest in a medium have extensive knowledge of who makes the games they like? That's what enthusiast users understand and care about. Which is funny: the people who actually would be motivated by brand loyalty are the precise people not buying things like Nintendogs.
