The most expensive game in my collection... Hmm...I'd have to say, Christmas Carol. That game turned out to be the fruit of a Faustian deal--it rob me of almost two years of life, made me miss Christmas (of all things!), and almost cost me my marriage. Not to mention a not insignificant amount of money in promoting and supporting the launch.In the end, I'd do it all over again; though I'd be more careful in keeping my marriage and holiday traditions. dZ.
