Box has a split corner / Many pieces appear unpunched and unused / I am unsure of whether this is complete

I received this in a lot of old computer games that I purchased. I'm not a fan of this type of game and don't know what should be in the box. If you're interested in buying this, you know more about it than I do. I took care to make sure everything was pictured. If it is not in a picture, assume it is not there.
