Kingdoms of Loathing (or KoL, as it is referred to) is a download-free game with graphics that consist of black-and-white doodles, with NPCs and player characters represented via stick figures. There is not much plot, just a basic quest to kill a witch (known as the "Naughty Sorceress") to staunch the flow of monsters into the land. The game prides itself on its originality and humor, not its combat, though battles are present.
Violence: Combat is displayed through a white screen with dropdown menus. Attacks will be selected via said menus, and a brief message (i.e: "You strike your opponent on the forehead with the flat part of your blade, producing a satisfying 'Thwok' sound.") followed by some onomatopoeia ("BIFF! BAM! POW!"), then a description of how much damage you dealt. Defeated enemies drop items and Meat, the game's currency (poking fun at how random animals will drop currency in other video games). One of the game's items is a "Bum Cheek", which is described as the actual severed cheek of a bum (homeless person) who attacked you. Said item can be worn as a hat. One of the available classes is "Seal Clubber", itself a parody of Viking-esque classes ("The Seal Clubber hails from the frigid northlands, because one character class always hails from the frigid northlands"). All in all, violence is described (as there are no attack animations) in the same cartoonish manner as a Tom and Jerry cartoon.
Sexy Stuff: One item is called the "Chainmail Monokini", and is implied not to cover much. Females are generally not portrayed as any different from males in the game, with the difference of females having hair drawn onto their heads. Players may pay 500 Meat to change their avatar's gender, and if turning from male to female, the description will read: "You hand over the meat (in more ways than one) and lie down. When you wake up, you feel.......different." Some innuendo in dialogue (such as the aforementioned pun).
Drinking, Drugs, Smoking. Beverages are present, but not in a particularly overpowering way. They provide passive bonuses, and your character can become drunk (this will have a mixed affect, barring you from some "Adventures" (battles), but giving you access to others you may not otherwise encounter. It also locks you out of many important activities, though. So, basically, Commonsense has once again blown this out of proportion. One can go through the entire game without drinking, really. One quest does, however, result in you taking hallucinogenic drugs and going on a "trip". But, this is generally treated as just another zone of the game.
Other Concerns: Females and males are treated differently in this game. For instance, males get a penalty for eating quiche, females get a bonus for wearing a certain pair of boots, etc. As I mentioned before, "Seal Clubber" is one of the available classes, which could concern some families (please note that seals are portrayed as evil in this game, which either improves or deteriorates the situation depending on how you look at it.)
Conclusion: A lot of the humor in the game is derived from pop culture, so those who aren't familiar with some of what they reference (such as stating "It's the end of your quest as we know it! Don't worry, I feel fine." This is a reference to a R.E.M song "The End of the World as We Know It") won't get the game's jokes (and really, that's the point of the game). However, they also parody Role-Playing Games (such as a quest to clear out a tavern basement of rats, to appease the inn's proprietor "Bart Ender". So, this game is best appreciated by gamers who are fond of MAD Magazine's style of humor. Younger kids COULD play it, but they might miss out on the game's most important aspect.
