Ryse: Son of Rome is a first step. That’s what it feels like, at least. Crytek’s Microsoft-published Xbox One launch title is exactly what it needs to be: simple, straightforward, and pretty. The sort of diversion that anyone, from gaming newcomer to joystick-twirling veteran, can spend a few hours with and end up with a sense of what their new toy can do. What it’s not is forgettable.
