Hey
Great Idea doing such a widespread comprehensive tutorial series for this, given that OpenWorld was just promoted at GDC 
Btw. porting to 4.8 shouldn’t induce too much trouble, mostly some changes to the override specifier and some undeclared identifiers from what i’ve been seeing in the log when trying to convert.
I guess you are waiting for a stable release though?
Im basicly just saying thanks and keep up the good work!
Greetings
Chris
