It's great game, but I'd make one small correction. (My OCD iscoming out... Lol)
Unless you prefer going through the painfully long and expensive process to purchase an automatic rifle (aka assault rifle), the semi-automatic is by far the most common rifle in the US wherever it's legal. It'd make more sense to use the term "semi-automatic" versus just "automatic."
Other than that, it's a pretty dark, but interesting story on psychological problems people face with grief.
