As a Unity3D game developer, I find tech jobs that get specific about what tools are used to be helpful to me. I want to stay in my toolset and do things I'm especially experienced with and good at.. there is, for me, a significant difference between using Unity3D and Unreal or making 2D games versus 3D games. Sure, I could move to other domains but I would be less effective (at first). I feel like this is a false problem with a few valid points that are blown way out of proportion.
