My Series X came in today.
First game I installed was Fight Night Champion.
First thoughts are that I'm not terribly fond of the home screen/menu. It seems needlessly busy, but I imagine that part of this is just due to it being different, and I can customize it down to being closer to my minimalist taste.
Not crazy about the controller right now, either. Also thinking it's just because it's new, but the sticks don't have the resistance I'm used to, and the face buttons could use to be a little clicker for my taste. D-pad is nice, as compared to having four directional buttons in the general shape of a d-pad. Muscle memory is definitely fighting me over the placement of the sticks, though.
Queued up some games to install overnight z and should have some time during "lunch' to fukk around a bit and get used to things.
