Halo Reach from the MCC on PC (Game Pass). One of the original ones I never played on Xbox. Quite enjoying it to be fair. Runs super smooth even with my GPU basically falling asleep at around 45% usage (and clocks of around 1200..) @ 1440p / locked 144FPS, although it feels like it doesn't like running at over 60FPS as the animations go a bit hinkey at times. Been a rough few weeks so nice to enjoy a bit of gaming again. Also having my PC now in the NZXT H1 and its spooky how quite it is..
