LaPtiteBete: Do you have some examples ?... :)
Sure... Call of Duty 4, even though it is fictional, it is still similar to current wars, which feels weird at times.
I played PAYDAY: The Heist a lot a couple years ago, but it made me really uncomfortable to play due to so many mass shootings in real life, so I stopped :-\
Yesterday I played Act of War, and it felt a little strange because it kinda feels like a current war.
It's not always about current events though... A couple times, it has felt a bit awkward to play games like Medal of Honor, because many of the levels are based on real battles that happened.
