Here's a rather fun little game that was made to promote the K'NEX construction toy line. Played a bit of it as a child and managed to keep myself entertained for hours with this game.

The main course however is a big, overhead, third-person, action adventure game in which you have to recover pieces to reconstruct a huge mining device that is invaluable to the mining race your main character belongs to.
