2017 has been the best year for the system so far for me, no doubt about it. Super Mario Odyssey, BotW, DOOM, and last but not least Xenoblade 2 made it fantastic and very memorable. Last year also had a lot of games I was interested in, though, half of which I haven't even touched yet.
My bet with The_Liquid_Laser: I think the Switch won't surpass the PS2 as the best selling system of all time. If it does, I'll play a game of a list that The_Liquid_Laser will provide, I will have to play it for 50 hours or complete it, whatever comes first.
