Yes, that's the problem. Very old tuts plus there are no tutorials with the basics what a gamedesigner needs, just the basics nothing more.
Best way would be 2 tutorials one just for the basics. A simple 2D platformer and a 3D third or first person shooter where you collect coins, using triggers and stuff including UI of course.
Playmaker was sold very often and in this 6 years of existence (?) there is no tutorial that covers the basics? Very disappointing. The documentation isn't helpful either and I paid for this tool 60 bucks...
I understand the very basics (variables, integers, methods, if else, loops and so on) of C# and can code just a litttttttle bit. I thought it will be a piece of cake to get into Playmaker but no. The search how to do something is so painful that I consider to find a solution in C#... that is obviously not what I and the creator of PM have in mind I guess...
There are tutorials on youtube but mostly such that you make your desired function and then there occurs another problem out of the first function that have to be solved. So you have another riddle that you don't know how to solve...
Please make a manual that you can work with, such I wrote "I want that Player pick up a coin" -> do this and this, like a dictionary or a library to search for actions.
Or just a project that covers most basics, stuff that you need the most when developing a game. It's always the same, movement, enemy, player, pick up, carry stuff, weapons, raycast for weapons, triggers to open doors or props (a chest), and so on...
