No.
GB and SW are fictional, which make them fun.
WW2 games are nonfiction (more or less), but WW2 happened 60 years ago, so WW2 Flight sims are kind of fun.
Not only is 9/11 nonfiction, I saw it live on TV the morning it happened (computer class, Mr. Bowman, room V105, first period. I'll never forget.. -uh, anyway, let's move on

), and the 9/11 Retaliation Campaign (nickname for the war in Afghanistan) is still going on and is definetly nonfiction (did you hear about the martyr guy who tried to blow up another plane with a bomb in his shoe?). So no, not funny. Don't.
