Xbox added pre-loading to the Xbox Game Pass starting with Crackdown 3 when it becomes available next year.
"One of the biggests asks we've had for Xbox Game Pass was to allow pre-load (pre-install) so you can download and be ready the second launch happens," Xbox Program Management vice president Mike Ybarra tweeted. "It's available now – and starts with Crackdown 3 on Xbox and Windows."

Microsoft announced at the X018 event in Mexico City last weekend that Crackdown 3, after much delay, will be coming out on February 15, 2019. But you can pre-install Crackdown 3 now so that when release day finally comes around you won't have to wait for it download.
Just because you can pre-install Crackdown 3 doesn't mean the game is complete however. "It's just a stub for when the final build is released," Ybarra tweeted. Capcom did something similar with Devil May Cry 5 this week despite it being months away from launch.
