I suppose my wording was funny. I was just referring to the fact that Crytek retained the IP when MS signed the deal for the game.
Nah my fault, I misread. I believe the reason for that is likely because Ryse was already a partly developed product back before the XBO launch, it was in development for 7 years prior to that. Microsoft wanted a high-quality XBO game quickly for launch, so Crytek with an already developed product had more leverage to retain the IP at that point. Microsoft just needed a quick game, arguing over IP might not have been feasible then.
