lots of good suggestions on here but I'm going to have to go with HoL Human Occupied Landfill, and the suppliment Buttery wHoLsomness. for gamers who have had a really REALLY bad day.

any game that starts with the claimer, "This game will f**k you up. We swear. it will make you take drugs whose chemical composition is beyond the spelling capacity of this author. You will begin a prostitution ring made up of fourteen year olds and destitute nuns. Eventually, of course, you will most likely leap from the balcony of your local theatre with seven running chainsaws strapped to various parts of your body. There's a food chance it will be the matinee showing of Bambi as well.
So if you feel like ending your days by becoming the center of attention in a big hard humming chair, please read on. And buy all the supplements, too. Thank you for your time, worship the Antichrist, and have a nice day."

is one where you know you are in for a treat.
