the conduit for its depth of customization and red steel 2 for how good it felt. After tweeking with the controls of both games it felt completely natural shooting in the conduit and sword fighting in red steel 2. I did really dig archery in skyward sword. For racing, the controls in excite truck were really good.
Seriously though, metroid trilogy should've adopted the conduit customization. Being able to adjust the dead zone was so key to an enjoyable fps motion control experience.
