Upcoming Godot Chapter + a question for you all

Hello all, sorry again for the silence...  just over a week and a half of summer left.  Then hopefully my productivity will go through the roof... or at least, not be awful!

Just a quick heads-up, I've been somewhat hung on waiting for at least the alpha version of Godot 3.1 to finish/revisit certain book chapters.  So instead of sitting twirling my thumbs I instead went down a completely different route than intended, working on a different chapter. 

Right now I am putting on the finishing touches on the Godot networking chapter, which should be available by this weeks end.  It covers networking, from low level sockets, to HTTP requests and finally using built in Godot ENet networking support.  Stay tuned for that PDF.

I'm also looking for some feedback.  I'm launching a "Hello World" game series on devga.me (which means you will again get early access to the text versions!) and YouTube.  This series is basically implementing a simple minimal 3D game, a revival of my bowling game concept.  You can learn more about the series here (https://www.youtube.com/watch?v=aGzk9BxBEFs).  The basic gist is to give people a quick, consistent introduction to game engines, enabling you to either quick start with an engine, or be able to compare workflows without having to get your hands dirty.

My question to you is, what 3D engines would you like to see covered?  My current intentions are:

Xenko, Unity, Unreal, Godot, CryEngine and maybe Lumberyard.

Are there other 3D engines you'd like to see get the Hello World treatment?  It seems (somewhat odd/shocking to me personally) that a fair number of people are interested in Torque3D so far.  Any other engines you'd be interesting in seeing get this treatment?  They need to at the least support importing 3d models, physics, audio and some form of scripting to be considered.

I am also hoping to do a similar series for 2D games, basically implement the same simple but complete 2D game across several game engines.  I need to come up with a game template to work with.  A suggestion in the above thread was a top down tank game... and I rather like that idea, but I'd love to hear from all of you if you've got any suggestions.

Oh, and thanks once again for all your support, it's greatly appreciated.  Especially through the summer doldrums!

Cheers,

Mike
