What’s considered safe in the board game industry by Hasbro? Releasing a game that plays nearly identically to a previously popular game, and using the popularity of the previous game to sell the new one. The thing is, the games often have new mechanics, some of which actually improve the game. It’s just nice to have a well known brand name to boost the attention of passing shoppers.
Given how little actually changes in the game play, it’s amazing how much Hasbro’s art and packaging divisions have to do.
