Evil Under the Sun (Wii)
The problem with this game is that there is no real sleuthing involved. You (as Poirot) spend most of the time walking around and around the island looking for clues or items when you don't have any idea what you're looking for. The game is basic point and click but while there are dialogue choices when speaking to the characters, it doesn't matter what sequence you select so the choices are essentially pointless.
To be honest I found it tedious. Finding the clues required stamina rather than any real powers of investigation.
