Yeah, Google "UDK".

WDID: Yes, it is pointless. Do you have any idea what sort of a difference it makes supporting extra dynamic lights? As well as different cards supporting OpenGL better than DirectX and vice versa.

EDIT: I've just been looking at the way Unity handles lights, and there is NO WAY you automatically get better performance. Unity adds an extra pass for every light. It's a great way to simplify their shader/material/light system, but since it's forward rendered this will generally be less efficient than a decently-written shader in A7.
