Football Manager has a bunch of logos/kits too, and you can download any that it's missing so you can still have official logos/kits for every team in the game if you want. That said, they aren't even the same genre. They may both be football games, but they're about as different as Fire Emblem Warriors and regular Fire Emblem are to each other, so Football Manager shouldn't really be considered as an alternative to FIFA's career mode. Way too different.
As for the rest of the thread, no you're a good person. FIFA's an awesome game!
I could try downloading all the missing stuff. Is it a hassle to do or can it be done automatically through Steam Workshop or something like that?
how may of them actually complete on the cart and don't require a download to complete the game so that you can play them?
All of them. They're not big games.
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.
