Keep in mind most "big" Switch 3rd parties aren't even out yet, the biggest one arguably is Bomberman
Soon we have Mario Rabbids, Skyrim, Fifa, WWE, Lego games, Sonic Forces/Mania, Battlechasers (not big but I am hyped) and a good few jgames like Nights of Azure.
So far we have had games like Cars 3, Bomberman, Lego City Undercover, and Disgaea 5.
And Disgaea has done fairly well considering it's niche market (110k pre orders)
