I have had a DK3 in my garage for a couple of years now, and never even once tried to accidentally shoot all of the bugs. It is a completely different game than I thought it was. It is actually a lot of fun when you play it right. There is a little Galaxian/Galaga feel to it even. The 3 bugs attacking in formation is so obvious now that I am looking at the game as a shooter instead of trying to figure out how it is a DK game. Once you start playing, that even becomes evident as you have different goals for each screen.
I still can't believe the difference. The DK3 is my girlfriend's, and I have been trying to think of a way to get her to trade it for a while. I am kinda glad I didn't get it done.
Definitely give this game a second look if you, like me, just thought you were supposed to push DK to the top.
So yeah, the buyer got a great deal on this game.
