Hopefully no one considers this spam. Yesterday I posted about an article I wrote about Congo for a local pinball magazine, and someone in the thread suggested I cross-post it to the Congo owners thread. I imagine it will have redundant info for many of you as you've already made the decision to buy the game, but hopefully it has a few little tricks and neat pieces of info you might not have known about.
