We actually looked at both options. But ultimately we chose to keep it back to basics. Since players use dual weapons (one on the Nunchuk and one on the Wii Remote) we decided not to use Wii MotionPlus as it does not enhance any of the Nunchuk’s controls. As for the balance board, since you can only have one per system, it didn’t make sense to use it because of our multiplayer mode and it didn’t really enhance the gameplay in a meaningful way to justify moving forward.
