RPS is all about giving respect to the long running franchises. Due to that, we have to give a seasonal heads up to to the latest installment of the Elf Bowling franchise, Elf Bowling 7 1/7: The Last Insult. Also it allowed me to narrow my definition of "casual game" to be "anything I can play effectively while talking game theory with Jim".
The idea's simple - North Pole bowling with Elves for pins. But you can control the ball, and pick up power-ups along the way. These are where the game becomes memorable - firing an over-sized ball with boxing gloves attack through a speed patch which makes the ball go so fast it leaves scorch marks has a way of being memorable. Bar the constant quips from the Elves, it's acceptable Christmas Cheer and the one-hour demo may make it perfect for a multi-player post-pub elf-bashing session.
