Today it might not be the case, but back when Microsoft offered Windows 10 for free as an update and I downloaded it, my PC became absolute shit. Stuttered forever every 20 seconds or so, and it tended to crash a lot each time it installed an update. Downgraded again to Windows 8, smooth as a baby's butt.
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.
