etb: As all great work of art, often the author do not really think too much about deeper meanings, but the readers/users/spectators get stimulated by it anyway.[...]
Are you sure this is how you want to phrase it? Most great works of art have no subtext? Let's test this then:
- 'Alien' is just a movie about a monster that kills people on a space ship. It does not allude to the horror of being raped, represented by the face huggers impregnating you through your mouth and the xenomorph that looks like a penis-monster with a penis-like tongue stabbing you.
- 'War of the Worlds' is a book about aliens from outer space invading earth. It does not represent the injustice of colonialism where civilisations with superior technology force themselves upon and make others subservient.
- 'The Thin Red Line' is just a WWII war movie with American and Japanese soldiers fighting in the pacific. It is not a movie about men who do not understand each other and therefore fear one another, nor is it about the tragedy that leaving your loved ones behind and what the horrors of war does to men. (The movie ends with a Japanese soldier verging on tears pleading for an American soldier to surrender because he doesn't want to kill him, but the American doesn't understand the command and believes he will be tortured to death if he surrenders and provokes the Japanese to shoot him. Wow.)
- 'Drive' is just a movie about a cool but slightly creepy guy who tries to help a girl he likes. It isn't a character study of a sociopath who tries be human but ultimately realises he can't escape his violent nature.
etb: [...] My point is, I am not sure there "IS" a meaning as Postal author intended. I doubt so honestly.
[...] My favorite game is Postal2 and really I feel sympathetic with the main character. To me it's really an exaggeration of the real world [...]
This is what we usually call satire, and that is perhaps all Postal ever was beyond it's gameplay. The first game is argueably putting the player in the shoes of someone who is suffering a violent psychosis, shown by how the game starts with people attacking him and he has to defend himself rather than the player deciding to go on a rampage, but it isn't really exploring this theme so much as using it to motivate gameplay. The second game is more focused on satirising a few aspects of early 00's Americana and doesn't actually say that Postal Dude is having a psychosis. He's just the snarky straight man in an insane world. Again, this isn't so much a theme as it is a way to motivate gameplay.
On this point, I agree with you. The postal games do not have a message. They don't have meaning beyond their gameplay loops. When anti-game violence activists storm the game developer office, it becomes extreme satire that is more of a joke than commentary. At most, we can glean that the developers don't like these critics and treat them like cannon fodder in their game. They are not pointing out a hypocrisy as is usually the purpose of political satire, they are only extending a middle finger.
Perhaps Postal just isn't a great work of art. Who would have thought?
