Unfair Games Company
The naming of the company 'Unfair Games' is symbolic of representing Sadie and Sam's fierce disagreements. Besides sharing their passion for designing games, Sadie and Sam do not agree on everything because they have different tastes and preferences on how a game's final product should look. For instance, Sadie wants the games to be artful and full of beauty and complexity. However, Sam wants the games to be easy and entertaining. However, at last, they always agree.
The symbolism of community service
