Corrected entry: At the end, the employee at the game store puts the Stay Alive game in a system that plays on the TVs in the store. Obviously, this helps the plot, but stores don't allow Mature rated games to be shown in the stores to adhere to the ESRB rules.
Corrected entry: In the scene where Miller is asking Hutch for advice on Silent Hill 4: The Room, Hutch gives him a strategy that only works on the first Silent Hill game.
Correction: Character mistake.
Correction: I've seen mature rated games such as Grand Theft Auto, Halo games and Carmaggedon displayed and demoed in stores that sell video games. Just because ESRB stipulates that games aren't to be displayed doesn't mean all retailers adhere to the rules.
