Microsoft's Xbox Game Pass is arguably gaming's definitive subscription service. Part of that reputation stems from the company's willingness to allow major exclusives to debut directly on Game Pass, along with a fairly impressive range of third-party Day One arrivals. However, something that cannot be underappreciated is the platform's variety, offering something for just about every preference or situation. Along with fantastic single-player options, many of the best Xbox co-op games are also on Game Pass.
