Destineer today announced Cate West: The Vanishing Files will be making an appearance on Wii. According to the description, the game will seemingly play as the PC version, but with a Wii remote. Players will help Cate compile evidence to help solve crimes and mysteries from the past.
Four screenshots of the game were released as well and are available in the media section.
I would guess this is a port from the PC version.
A lot of games like this have been showing up lately. I remember playing a demo of one on my DS, then one on XBox 360 Live. If this takes off too, it might be a good idea to try a "Where’s Waldo" video game again.
