Alfie Vaughan recreated minecraft in blender video, and shows how he did that.  REally awesome.

I stumbled across "film stops" Video about all the great videos to watch categorized by each part of blender, that will let you learn all the most important Diciplines to to do actual do 80% of all your work.  Watch the videos 2 times at least.  Once to watch the video and get an idea of what the Creator is actually telling you.  Then Open blender, and rewatch the video while following along. :) Hopefully you will have the same result as what the video is helping you learn.

This seems interesting . I'm not sure how they got their demo scene looking so photo real.  Combined with the realistic camera motion, their scene looked photo real.

These are two very good videos that will get you off to the races, if you want to make Star Wars type dog fights.   (You could replace this with whatever ships you have though.) FYI any clouds will make your renders super slow.  Adding vfx pre rendered will help with this, but you have to be careful for simple camera moves if you do that.

These are all the Pwnisher challenger compilations.  

When you watch them, try to see what works and doesn't.  You can tell basically; after awhile what the good ones are.
