In Fragile ~ Sayonara Tsuki no Haikyo ~ you take on the role of Seto, a boy living in a desolate world. Traces of human life are gone and all that remains are modern looking ruins. Seto searches to find out what happened with a flashlight in his hand. Players use the Wii remote to point the flashlight on the screen. Seto also carries a metal detector to scan for hidden items in the ground and a tree branch in his left hand. The stick is in most of the screenshots over at Famitsu so it must be a significant element in the game. It looks like the branch may be one of Seto's weapons, but I can't imagine it being much help against the demons lurking around in the post apocalyptic.
Here is another nifty bit of info, Tri-Crescendo, the team behind Eternal Sonata, is developing Fragile ~ Sayonara Tsuki no Haikyo ~ as their first Nintendo Wii title.
