A while back there was a thread that discussed several MiceChatters' favorite 8-bit Nintendo games. I was surprised when no one mentioned "Adventures in the Magic Kingdom" seeing that this is a Disney site. While it wasn't my favorite game, it was definitely memorable if you knew the parks.
Well, I was browsing YouTube tonight and found some videos relating to the game. Here are two links that will walk you through what this game exactly was. In my opinion, it was an ambitious game that was just too darn hard.
If you don't mind a lot of swearing, but want to laugh and see how challenging this game was, look on the related videos section and find the video labeled "Games That Suck - Adventures in the Magic Kingdom." This video is not for kids or people who are put off by unnecessary foulness. Also, it's a little mean to Mickey and Disney. But, it does have it's funny moments if you remember the struggles of the game.
Here are the two links to the clean runthroughs of the game.
