A meta post I seen a while ago argued that a question should not be closed in regards to asking about a game that has not been released, if the game in question is accessible.
This mostly concerned games that are in beta testing, where the game in question is publicly tested, and it would be feasible for somebody else to be able to answer given knowledge and understand they have from having played the game as far as the developer allows in said beta testing.
I signed up for the Battleborne beta, recently, and part of the conditions in which I was allowed access was that I would not disclose any information about the game.
From my experience, this is common in any form of early testing. As the player, one of the conditions in which you are given access to this early model of the game is that you will not disclose how the game works to people outside of the beta.
How do we feel about asking/ answering questions that involve providing information from experience where the initial agreement prohibits our disclosure of said information?
