Hello!
I'd like to purchase a Personal License but I have a question.
Does the Personal License include a Steam code to activate the Engine on Steam?
I like having it there but I'm also interested in purchasing the "Beginner Pack 2" bundle which is only available to this site.
No.
The licensing systems - here and Steam - are entirely separate processes. Purchasing one type of license doesn't entitle you to get the other, unfortunately.
