Third party games come out way too frequent and they are always the top best selling games. A lot of people can only afford one console and if Nintendo's top best selling exclusives come out once or twice a year while the top best selling third party games come out ten times a year that is a big problem for Nintendo. The Wii U failed and a lot of it has to do with little to no third party games and being more expensive than the competition (ps3 and 360). The xbox one/ ps4 will be $250 with all the third party games that people want.
I feel like Nintendo Switch could've made a case for it's system if they made the system cheaper (around 200 dollars).
