N-Fusion and Vir2L Studios (Bethesda's sibling) have announced Medieval Games for the Wii. As the title suggests you will be able to compete in a number of medieval events such as archery, catapulting, jousting, storming castles and fighting dragons with your friends.
Hopefully N-Fusion can bounce back after the horrendous Hour of Victory and perhaps a medieval mini-game festival is something they will handle better than a World War II FPS. Apart from Medieval Games N-Fusion are also working on another Wii game - Martian Panic for publisher Empire Interactive.
