First, Silicon Knights sued Epic Games, alleging that Epic’s Unreal Engine 3 had done “serious damage” to SK’s long-delayed Too Human.  Later, Epic fired back with a countersuit, in which Epic claimed that Silicon Knights wanted to use the engine without paying for it.

Now, longtime Epic partner Digital Extremes, in the middle of development of its similarly delayed Dark Sector project, has come forth with its own complaints.  Game director Steve Sinclair explained, “A lot of promises were made about the Unreal III engine, particularly on PS3. But as we see now, the time frames haven’t been met and now a lot of games using it are being held up.”

Now that two developers are on the record about problems with Unreal Engine 3, we wouldn’t be surprised to see loads of developers come out of the woodwork with similar grievances, both real and imagined.  The situation is likely to become ugly really soon.
