It's certainly an appealing deal to me, so I can understand if it does well.
I'm primarily interested in Gears 5 to play the campaign, so the idea I can pay for a month of Game Pass and have a comfortable 30 days to complete the campaign (as opposed to renting at a place like Redbox where fees start to add up pretty quickly on a daily rate) sounds quite nice.
Currently have some other games to go through on my backlog before I play Gears and decide what I want to do, but definitely appreciate this option. Also nice to be able to do this on PC.
