I went into a 'Game' store here in the Uk a few years ago, and picked up one of those dubious looking five pound specials. I forget the name of the game but it was supposed to be about taking countries as they were in 1999 and running into the future. It said the stats were collected from reality.
This sounded like a concept that if nothing else would leave me better informed about regional economies and geography, so I bought it. However, it was so unbelievably buggy, and disconnected from the real world I gave up after a few attempts. In fact it was so bad that I trekked back to the store. "I know I can't get a refund just because I don't like something but for the love of humanity please don't sell this game to anyone else." The manager was so pleased to be given some useful feedback he let me have a full refund, without presenting the disc, and an apology.
