It's the battle of the genders in this expansion pack. Use it to collect Fims of either gender. But don't place a Fim in the wrong gendered build, or bad things will happen! Things like: your main game losing all Fims of the same gender as he or she whom you misplaced. Things like: Your game downgrading from "The Fims 5: From The Ground Up", to "The Fims 4: A New Beginning". And things like: You clicking on the "PLAY" button, only to be prompted to erase your save data and have no choice but an "OK" button. Just kidding, none of those things will happen, but why not take what I said and use it to scare your friends and family into staying organized in their gameplay. That would be rather laughable. Anyway, I made this expansion pack to compliment my new song, called, "Boys Versus Girls". Long story, but you can learn more about the story behind the song at the following web address. http://fbenson.webs.com/apps/podcast/podcast/347927 The "Boys Versus Girls" expansion pack features the most prevalent riff in the whole song. Please enjoy, and happy Fimulation!
