Could be anything - Xbox, PS3, Wii, computer, etc. - like a game you hated, or dying after nearly taking down a boss, or losing a game of Madden for money, whatever. Please share your gripes!
Mine was buying Conan for Xbox 360 ... played it twice, hated the controls, the lame enemies, the linear levels ... but most of all I could not stand how a favorite like Conan could be butchered in a video game. Bought it for twenty and sold it for $2 trade, and only too glad to be rid of it. UUGGGGLLLYYYY!!!!!
