Gary, it's your game then, inspired by (zzo38) A. Black.
One person makes a suggestion, but does nothing with it.
A second person takes the suggestion, pounds it into shape, changes it, gives it a theme and gives it back to the first person, who takes it, and with an offhand gesture and no apparent thought, tosses it back out. Questions about this secoond incarnation of the game prompt person 2 but not person 1 to say 'I'll fix it, by doing this, this, and this.'
Two questions:
1 - Which of these 2 people above do you [who are reading this right now] think will make the board changes and other necessary corrections?
2 - Whose game is it, really?
I think we get into problems with the term 'game inventor'. I prefer the term 'game designer', and always have. If a playable game results from this, is it because of the 'inventor' or the 'designer'?
