Gears 5 has been a hit for The Coalition so far. Despite server issues (something the team is addressing with updates), the latest game in the Gears of War series has proved to be very popular, especially on Xbox.
In fact, it's been popular enough to become the most-played title on Xbox One, dethroning the giant that is Fortnite. This means it sits above Minecraft, Grand Theft Auto V, and FIFA 19 as well, which is a real feat.
You can see why we liked the game so much in our review, but it's also worth noting that it's included with Game Pass too, so that might be what's boosting the player numbers, as well as word of mouth from the early release for Game Pass Ultimate members and Ultimate Edition owners.
