It's WAR! Not real war, with bombs and screaming, but tech war, with payment models and indie schmoozing. Last night, Epic unveiled their subscription plan for Unreal Engine 4, offering the binary development tools and engine source for $19 per month. Now, Crytek have announced their own "CryEngine-as-a-service" subscription model. It has a couple of advantages over Epic's plan: it's cheaper, at $9.90 per month, and it's royalty free.
