Ryse: Son of Rome is coming to the PC on October 10th for $40. I'll arrive bundled in with all the DLC included so far and a full soundtrack (for pre-orders), as well as 4K resolution support.
In case you missed our coverage during the launch of the Xbox One, the campaign, the core of the game, is not very good. But if you're interested in the gladiator arena portion of the game (which is actually fun), picking it up on a Steam sale wouldn't be a bad idea.
A very, very deep discounted Steam sale.
