Congo was sort of a forgotten game when it came out in 95, completely overshadowed by AFM which I guess is understandable! Suffers from a failed movie theme and some really grating call outs, but it is has some really good shots and is arguably a good looking game.
To me it falls in the low $2K category for an average machine, bump it up for something extraordinary. I would like to get one someday, but the prices will probably have to fall before I'll find one at a price I can live with
