I have a few but my, by far, my biggest one I owe to KSP.
Kerbal Space Program has RUINED watching the way spacecraft in movies move.
I know KSP could be more accurate at times (such as space should be silent but that would be really boring and this is a game)
but I feel like it at minimal gives me an idea, like how a driving game is to driving.
Not the same thing at all but assuming it was a somewhat realistic driving game it could give you
enough of a feel to then know when something is VERY wrong what the way a car is moving. (Cars don't drive sideways down the road, that sort of thing)
Prior to playing KSP, I logically knew that the movement of spacecraft in movies was often not that accurate.
But it did not punch me in the gut as oh, that's just not possible.
Now the way spaceships in movies move around often just looks so silly that they break the suspension of disbelief for me.
Thank you squad... I think.
