"The Star Wars: Monopoly game was released in September, months before the movie's release, and Rey was not included to avoid revealing a key plot line that she takes on Kylo Ren and joins the Rebel Alliance." - Hasbro
Are you in agreement to this excuse? Well, why not. There seems to be some truth in the statement. Though the Force will not be as strong for this one. But maybe not. Because this gives Hasbro a great excuse to come out with another version of the Monopoly game which will now include Rey Skywalker.
Hopefully, to join Darth Vader, Luke Skywalker, Darth Kylo Ren and Finn (FN-2187), will be Rey Skywalker since she is after all the lead star of the Star Wars: The Force Awakens movie. This can be clearly seen on the movie posters. Lucas Films and Disney has made it very evident that Rey has a lead role. Though it would really have been a spoiler if she was seen using a light saber as a weapon. But that could have been easily avoided if they just let her pose with her original weapon.
Daisy Ridley also deserves to have her spot on all the new Star Wars merchandises. Girls who adore her as a role model would want to play with her. Even boys with raging hormones would want to "play" with her image. lol!
