Your daily dose of drama is provided by the fine folks at Crytek and Cloud Imperium Games.
A Cloud Imperium Games rep has responded with the following statement to Gamasutra: "We are aware of the Crytek complaint having been filed in the US District Court. CIG hasn’t used the CryEngine for quite some time since we switched to Amazon’s Lumberyard. This is a meritless lawsuit that we will defend vigorously against, including recovering from Crytek any costs incurred in this matter."
