Postal 2 is a notoriously bad videogame. Some people liked it when it launched back in 2003: PC Gamer, according to a Metacritic roundup, scored it 79%, calling it "a nonstop tour de force of insulting insanity." Computer Gaming World, on the other hand, handily summed up the more common consensus, rating it a flat 0 and declaring that "until someone boxes up syphilis and tries to sell it at retail, Postal 2 is the worst product ever foisted upon consumers."
The situation is somehow clearer yet more confusing on Steam, where Postal 2 has amassed an "overwhelmingly positive" rating across more than 71,000 user reviews. Irony is obviously a factor in that, with user reviews like "better than Cyberpunk" and "you can piss on people," which is doable when a game is regularly available for $1 (and sometimes free), as is the case here. Still, that's a lot of people who own Postal 2, and according to Steam Charts it's put up better player numbers over the past 12 months than Marvel's Avengers.
