I definitely agree with 2017.
2018 definitely was an improvement even if the games did not rate that well (Sea of Thieves and State of Decay 2). But, Forza Horizon 4 looks to be the ultimate arcade racer for this generation.
I am positive Crackdown 3 will rate better than Sea of Thieves at launch, Ori 2 will be no doubt be a highly rated game, and Gears 5 is definitely going to be a solid game. Add to that the cross platform game Outer World, and MS definitely looks better in 2019 then 2018.
