I just want to ask, if I understood you correctly. Perhaps the 15-20 players are only newbies who just started a new game to see what it is about? And accidentally, because they are new at RN they don't know what to do with the "start-up" vouchers and money and they simply invest everything in "our" factories? Well, to be honest, I do not believe in easter bunny or santa claus any more.
I will ask my team mates to comment on this as well and we will see, if they want to comment this too.
