What does Steelcase Edition mean?

I'm considering the video game "to buy the dwarfs": https://www.amazon.de/...01MS13EL6/

As you can see there are two different versions, one the standard and one the "Steelcas edition".

Is there a difference in the game?

Why is one with pegi from 12 and the other from 18?

Or what's the difference in general?

Steelcase simply means that the shell made of aluminum for collecting is usually also with special imprint

Why does she have another age restriction at pegi?

No idea. Here in Germany are interested and only the USK. And that's 12 for both versions.

Please correct me, but steel means steel… What does that have to do with aluminum?

guut, the chief of the steelbuddys also collects stuff of alu e.g. His planes… But still

But steelcase itself sounds better, which is why it has become established

Steel would increase the price

It shines like steel and yes to sell it better
