Actually no, but the result can be similar.
Nintendo follows an idea about games. These ideas come from in-house and they produce games following their ideas. With the NES/SNES and to some extent N64 the 3rd-party producers were following the blueprints Nintendo layed out, which is why there are significant 3rd-party games on these consoles. But later on the game industry started to follow more mainstream trends and dismiss the blueprints Nintendo layed out. There are exceptions, Just Dance for instance followed Nintendo and refined the concept and is now a staple of the video gam eindustry making a lot of money. But as nowadays most 3rd-parties just follow the mainstream trends often Nintendo is the only taking advantage of their consoles features. Thus the impression theys make their consoles only for their games.
