There's an incredibly strong push for games to adopt open-world appraoches to their experinces, but this often doesn't mean that the game will immedaitely be better. Rise of the Tomb Raider acts as a perfect lesson about pacing versus freedom.
Total War Arena is not some dumbed down battle mode or a quick cash grab. This is a well thought out multiplayer experience that brings the best parts of Total War together and makes them better. The result? Total War.
