GT Racing Motor Academy, where I did many car interiors in Photoshop in precise detail required by car constructors. I also got to work on several car exteriors in 3DS Max. See below for some examples:
Other published titles I've worked on are TV Show King Party for the Wii, TV Show King the wiiware version where I worked on characters, environments, special effects (particles and lighting), game assets and menus.
There are of course several currently in production titles and also unpublished titles I cannot give examples for, but I have worked on adventure platformers, sci-fi first person shooters, card games, board games, social games, and many game concepts and pitches.
