Reason for the low sales of 3DS is simple, it is INCREDIBLY underpowered for a device in 2014, especially with all these ultra powerful phones coming out.
A system comparable to PS2 in terms of power and with such a low resolution screen and expensive games for a portable device in 2014 is bound to be niche, and it probably has sold to 80% of all the people that wanted one. The only reason its still surviving is because of its library.
