It's not that great, the switch was made for competitive portability. There's really no games that take advantage of this feature besides puyo puyo Tetris, Mario kart and your pick of street fighter/retro game. All other games are single player games that can be enjoyed while docked. Or are already on other platforms. Splatoon definitely a big one and ARMS is going to take a while to establish a fan base willing to duke it out locally. NBA playgrounds was supposed to make a splash but the hype and excitement has been buried by patch delays and lack of multiplayer.
