In fact, any console is viable. Be it the Switch, the PS4, the XboxOne or even a portable like the 3DS and the Vita.
For quite some time ( about 2 years) I only played on the 3ds. It was my main console and I had tons and tons of fun with it.
In my country, videogame is expensive, so most people go with just one console or just a PC. Not many have more than one console.
