Because Oberon had clocks set in regression testing that match PS4 and PS4 Pro GPU clocks. Doubt MS would have any reason to do that unless XSX is backwards-compatible with Sony consoles too.
Which would be insane, but very unlikely
Some people take MetaCritic waaaaay too seriously. Some of my favorite games of all time would probably score only "okay" on Meta; doesn't take away they're some of my favorite games ever made.
At the very least I can get into detail why those games are my favorites with my own words; people who cling to Meta religiously can't do the same without quoting another reviewer, even for the small stuff xD (or they'll use the same talking points with nothing new to add to them).
I mean some people prefer Mario Sunshine over Mario 64. Sonic Adventure over Sonic 3. Parappa over UmJammer (BUT on this one I gotta say UmJammer just
destroys Parappa. Sorry not sorry x3), etc. Perfectly fine, it's not like having a preference means you're attacking other people for having their gaming preferences
