I totally disagree here!
Ideas are cheap and everyone has tons and tons of them.

Being able to turn a plan or an idea into a working game by investing time, effort and pain divides dreamers from game makers.
Dejobaan games might be simple or better said "achievable" but they went beyond talking about creating games to actually create the games. Huge difference!
Making games is plain and simple: work....lots and lots of work.

I see the point why unity might be more attractive to them then GS and I think right now this might be a smart change (until gs closes this gap maybe).

Good luck and cheers!!!
