To clarify things even more, the game was not any good. Some people list it as one of the worst games ever, but that's probably extreme. After paying $50 for this, do not expect you will enjoy playing it. It's like paying $50 to buy the Star Wars Christmas Special.
Actually I think ET gets a bad rap. The game itself is decidedly average, but it's fun in short spurts and has some amazing graphics (for the 2600 anyway). The problem is that it's also buggy as hell due to its rushed development cycle (6 weeks from start to finish when most games took 3-5 months) to meet the Christmas buying season. The biggest issue is that the collision detection with the pits is wonky and it's too difficult to tell what parts of ET can touch the pit without falling in and what parts can't. Add to this a nasty bug that makes falling back into pits after you levitate out a very common occurrence (you need to move down after levitating not left or right which would make sense) and you've got a very frustrating game.
If you've got a 2600 handy or an emulator, I suggest giving ET a chance. If you look here ( http://www.neocomputer.org/pro...) you can find an explanation of all the bugs in the game and download a bug free version of the game which makes it much more enjoyable (although it's still an average game).
HELP!!!! I'm being held prisoner in /usr/games/lib!
