Oh, I know. I headed a major project which involved usurping the root level of geometry in the Unity engine and injecting massive amounts of data into it and we actually found some major flaws in their underlying logic which only would come up when you hit the levels of throughput that we were dealing with. Getting them to admit to the fault was pulling teeth, but they did fix it once they were confronted live with the issue. So that's good on them at least. But that aside, the project went well and the tool at the other end is nothing short of incredible. I'd still rather work in Unity than Unreal for most of the types of projects I tend to do.
