Workshop

You would put so much effort into the game itself, rather than searching for someone to blame. There will always be people who are dissatisfied with something (especially if there are those among them who scrutinize everything under a microscope just to find a flaw). If you try to please every "expert," you'll go crazy. Enough arguing, it's time to release the game.

The only thing to consider is that if the setting is unclear to players, the GM will have to do a lot of extra work explaining certain things to others during the game itself. And that will be much more time-consuming than writing a brief history at the beginning. And there is also a risk that not many players will join.
