To me, the whole narrative of Gears 4 seems entirely pointless, and it showed through the campaign. There were barely any exciting or interesting things to see/do. I don't know, the atmosphere didn't feel as impressive as in the original trilogy.
However, the multiplayer is fantastic as always, I just can't get enough of it even seven years after I originally played Gears 2.
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.
