Back in 2011 I was a game tester on Hasbro Family Game Night 4. Definitely not an official spokesman here. It was so bad that we opted out of even having public reviews for the game from the large review sites.

Morale went way up once we released the game because everyone was so sick of working on it and knew the game was terrible. It was a product of having a low budget and tight deadlines. Sounds like my experience lines up with most of this Reddit discussion.

I think it may be different if, for some reason, the team is convinced their game is amazing before shipping. But in my experience game developers usually know if their game sucks.
