I own Congo and Shadow. I got to go with Congo for pure fun factor but they do make a nice pair. Shadow is a great game but think I would get very frustrated with it if it was my only pin. Congo is a little too easy but so many cool features. I never get tired of playing the cool modes. I do wish there was a little more challenge to the lower playfield but at least it looks cool. I like BSD but not the theme. It is a pretty good game for the money, though.
