I've been using this engine for almost two decades and have released several games with it.

I started just before the time A6 came out. Everything worked back then, but I start all my projects with a blank script right now, so I'm not sure how the tutorial levels are working.

Materials, and pretty much every other thing in this game requires editing a text file. That's called scripting. If you do not like, or are unwilling to learn scripting, then I would agree that this is not the tool for you.
