Perhaps difficult to find now, this game is worth the cash you'd find it on eBay or Amazon for.
Playing Abe's Oddysee, you are tramping around Rupture Farms, experimenting with the buttons. You press a certain button combination and a flatulent sound is heard. Your brain goes into joy-spasms. Did --- did the lead character just FART? You try it again. Abe farts again. You cry tears of joy. Then you find a sleeping enemy and fart on him. He instantly wakes up and fillets you. You don't care --- ABE CAN, NAY, MUST FART AT WILL. When you find out that flatulence is integral to beating the game, you just laugh even harder.
