N-Gage Games
The first adventure game for N-Gage, Dirk Dagger is set in the world of a traditional 1940s-style private investigator. Rather unusually this title lets you explore the game world using the phone's camera, and it has been designed entirely with phones in mind.

This game takes place shortly after the events of the film Star Wars Episode III. You play Darth Vader's apprentice, who must help destroy all of the remaining Jedi as ordered by the Emperor. The gameplay involves a lot of combat, but with an unusual interface that uses the phone's keypad to make particular shapes.
