i think the Gamepass shines the most for coop games. If you have a friend group you regularly play games with it there can be an issue of the different spending habits and willingness to buy games between everyone. Often one person will try to motivate others to get a game and than it gets played a few times and shelved.

The advantage of sports games is probably that most can be played coop, also there is a huge playerbase there that loves to buy lootboxes. Easy way to get whole friendsgroups signed up. I myself dont really like sportsgames that much, at least not if they are by EA.

Though I do hope that gamepass keeps getting more coop games. Especially more couch, casual and partygames. They do already have lots of survival and crafting games so far, which is great.
