Ex-pro baseball player and dog Rusty Slugger owns a sports shack. He’s broke with 10 puppies to feed, so he offers a variety of baseball mini-games for sale, themed around the simple pleasures of baseball. Players can bat, pitch, catch and even umpire. The initial software containing a part of the first mini-game is free, but players can purchase additional mini-games in a unique way: by haggling to lower the real-world price for each downloadable game. Additional games start at $4 apiece, but giving Rusty items or listening to his problems might improve his mood and motivate him to offer steep discounts.
