* CreatorBacklash: RWS has all but disowned the third game, dubbed it "Akella's ''Postal'' Spin off", and has pulled it from its store.
** Vince Desi had previously promised the game would not have DRM. The final version does. Just one of many things Akella did.
* HeyItsThatGuy: The film version of the Postal Dude is played by Zack Ward. Guess [[Film/AChristmasStory Scut Farkus]] ''really'' didn't turn out so well after growing up.
* TheOtherDarrin: The Postal Dude was voiced by Rick Hunter for the first two games. For ''Postal III'', he was replaced by Corey Cruise - likely [[ExecutiveMeddling another cost-saving measure by Akella]], considering there are still some lines recorded by Hunter hidden in the game files.
** Rick made a return to Postal 2 when it was updated with additional content and voice clips.
* TroubledProduction: Postal III very much so, according to the RWS website, things were going well with Akella at first until the Russian economy took a downturn, forcing Akella to lay off their A-team that was working on the game. RWS admitted they should've pulled the plug at that point since they knew there was no way Akella's B-team could possibly finish development to their standards, but they soldiered on anyways and Akella took more cost-cutting measures due to running low on funds. To top it off RWS were unable to oversee the last 12 months of development on the game, so it's no surprise it ultimately turned out the way it did.
** Postal 2's recent patch (December 2013), the first one in 10 years. It had a slight delay, but is finally out, adding a lot of things to the fray, and making Apocalypse Weekend a full part of the main game.
* {{Vaporware}}: Postal III was announced in 2006, with very few screenshots or videos being released since then and the official website being mostly filler. In October 2011, the game finally appeared on Steam's store under "Coming Soon" with the release scheduled for December. The exact date was finally revealed as December 20th, although the game was only available from the Running With Scissors online shop until February 2012.
* WhatCouldHaveBeen: Postal 2 had a some things that were either cut from the game or scrapped. Of course since the game is medium aware, it has a graveyard for them. A list of these things are:
** A meat gun, brought back in ''A Week In Paradise'' mod.
** A staple gun, brought back in ''AWP'' mod, with the meat gun.
** A rebar gun.
** Fire seeking cats.
** Fetuses with guns.
** Rape clowns.
** "Teen sniper". The name of an arcade machine in the game, possibly a planned mini-game or an enemy.
** Pigeons.
** The Dude's father as a zombie, to quote the grave: "Zombie Dad".
** And last but not least: The games original plot, before it became what it is today.
