Now that 3ds Max 2016 is available for download I'm pleased to announce a set of 30 sample MCG tools and 80 new compounds that you can download, use, and learn from!
%userprofile%/Autodesk/3ds Max 2016/Max Creation Graphinto your Windows explorer.
If you have any other compounds and tools installed, be sure to back them up first, in case some files in the zip package have the same name as existing files. When you restart 3ds Max you should see a number of new modifiers in the modifier pull-down. Each name of the new modifier starts with "A" (e.g. "APush"). There will also be a new category in the object creation panel called "Max Creation Graph" with several new tools.
I have also created a sample test file that you can load once you unzip the tools and restart 3ds Max here: MCGSampleTestScene.zip.
Your comments and questions are certainly appreciated, enjoy!
