Why there is no 2D top down game tutorial/others?

So i have asked this question before but it seems they have really nothing or a full game basics tutorials like unity forum does.

Example: http://unity3d.com/learn/tutorials/modules

yeah unreal has awesome tutorials. But why don’t they teach someone by making a game? I think that approach is better and keeps more interesting.

This is a pretty old question, but I just wanted to stick this out here in case someone else came across it. This should get you started in the right direction. https://docs.unrealengine.com/latest/INT/Engine/Paper2D/HowTo/TopDown
