the point at which you must give up all skeptisism, and just accept what goes against all that you think you know.

A term used that is usually used in the context of entertainment, which can include reading, video games, television, and films. It refers to the reader/watcher's ability or desire (or both) to ignore, distort or underplay realism in order to feel more involved with the game, film, or book. This is a very common practice in many action movies, some books, but probably the most in video games. It is usually permitted and ignored because most people don't care about realism in their entertainment. It's also much more difficult to program a realistic game with highly realistic damage scales, movement, targeting, and more. Some games which are meant to be silly (grand theft auto) don't require much of this, because the entire atmosphere revolves around the less-than-serious style. However, some others attempt to be serious but fail to relay such. This still does not ruin the feel for most, though.

Some people have poor suspension of disbelief, or just don't prefer to use it. These people usually don't care for casual 'shoot em up' games unless there is a huge element of humor and stupidity that is integral to the game itself. They are sometimes perceived as tight asses, but in reality, they just prefer to keep their unrealistic games silly and stupid.

Sometimes, fan boys will take their suspension of disbelief too far and proclaim blatantly unrealistic things to be realistic in an effort to validate the game against 'invaders' who simply assert the truth.
