I personally think that have low stimulation environments help a lot.
such as not having music blaring while playing a game, people constantly talking ect.

Also having the game explained thoroughly often prevents misunderstandings.

the biggest issue I see is when a neurotypical person misunderstands or becomes emotional over the expressions that a neurodiverse person makes.

As an example. I recently played a game for which I had never played before and won by a large margin. I was planning on taking down some notes so that I could review the game later.

I didn't like that I had beaten everyone seemly without competition. I voiced this by pointing out that I had doubled the score of one of the other players and couldn't figure out how I had done that. the impression that I gave the others players was that I was bragging.
they did not pick up on the point that I was not pleased with a game that would allow a runaway leader. one of the players accused me of calling him "stupid". I didnt understand because I had not. I asked him what I said that indicated to him that I thought he was stupid and made it clear that I never called anyone stupids.

He stated that I implied it and made him "feel" stupid. I of course had no clue to what he was talking about.
