From all the tutorial requests here, it seems the best approach might be to make a small game that introduces these subjects in full detail, enough to get started and enough to have confidence in the next steps with evolving them. A complete modern game might incorporate all these things(minus a few key select specific requests like tank controls.) and it would make a large tutorial set but it would also make a very tutorial complete situation for the unreal engine 4. Which might make it the definitive tutorial to go to for those getting started.
My request would be to see something like that, a start from scratch to complete game that introduces the many facets the engine can provide at a basic level which would leave someone with enough confidence to then go out and explore the features in full. Video tutorial would be preferred.
The most robust version of pong anyone has ever seen ? 
(or maybe 2 player Breakout so more physics examples can be made .)
