Wanting to play some no-holds-barred kitchen sink gaming, but aren’t sure where to start? Your worries are over! Simply start with any setting—Greyhawk, Eberron, Imperial Rome, The Roaring Twenties—and follow the simple steps below. And behold—Instant Kitchen Sink!
1) Playing in a fantasy game? Add sci-fi. Playing in a sci-fi game? Add fantasy. All others: add both.
2) Choose an indigenous life form. Give them some manner of natural laser, force beam, plasma burst, or heat ray. Other types of ray (gamma, death) will also suffice. Repeat as desired.
3) Choose two or more indigenous life forms, and combine them into some sort of wretched mutation. Repeat as desired. (Example: dragons and slugs give us the dread Slagon, a scaly monstrosity which hates salt and leaves a fiery residue as it oozes across the landscape).
4) Add a Mutations Table. Use it.
5) If you have guns, give at least some of them mystic, sword-of-legend type abilities. If you have swords of legend, give them pseudo-scientific, gun-like abilities (example: Excalibur, but Excalibur generates a mini-gravitational field to rend and tear opponents. Or something).
6) If there are gods in the setting (and this being kitchen sink, there should be!), they should have statistics for combat, if not be members of an adventuring party outright.
7) Choose 7 different historical eras, books, movies, cartoons, RPGs, your choice. Choose a character from each of those, and drop it (or a similar character with the serial numbers filed off) into your setting.
8) Somehow, somewhere, people are ruled or enslaved by apes.
9) Even if the entire world has been devastated and isolated by the plague, Kung-Fu never dies out, and will be known by robot and man alike.
10) More Lasers! (pay careful attention here. This never fails).
11) Take it to Eleven.
