My gaming group just wrapped up a Cold City campaign. It was fun, and we liked the setting, but afterwards the other players and I were unanimous in our dislike of the game’s system. There were some good bits, but too many bad bits getting in the way. For example, stats increase when you succeed and decrease when you fail, and if they decrease too far (which can happen on the turn of a single roll, especially if you were a min-maxer like me) that leads to a downward spiral and then it’s almost impossible for your character to become competent again.
Another player suggested that you could play a campaign with the same setting in another game like The Dystopian Universe Roleplaying Game (a Fate game). He was probably right, but I’ve never played that game, so I’m going to hack Cold City for Cortex Prime instead. Enjoy!
