My list would probably be topped with Fish Tales, Congo, The Shadow,and Bram Stoker's Dracula in that order. If we're considering "bang-for-your-buck" then you can probably flip The Shadow and Congo. I am not including White Water as a B-list game, based mostly on price. Once you're over $5k for a players condition game, it better be on your own personal A-List.
Quoted from IdahoRealtor:Congo is fun, but too easy.
What percentage of games were you getting Super Multiball (100-diamonds)? Congo is deeper then BSD and game times are longer, but I almost think they need to be since it's a much deeper game. I've owned and liked them both, but I just wouldn't call Congo "too easy".
