The New Gamer might not have enjoyed their stay at Hotel Dusk: Room 215, but they appreciate the work put into creating its memorable characters. Adding onto the unique visual style, each individual has a rich set of expressions and postures to communicate with. When one of the hotel guests describes a mannerism of the game's protagonist, you know exactly what he means by "that serious look in [Kyle's] eyes."
Sonic's toe-tapping idle animation and King Hippo's falling shorts were also cited as great examples of unforgettable character details. Simple idiosyncrasies like that stay with you long after you've finished playing a game. What unique traits have you seen give a collection of pixels an identity? Was it Midna's sigh? Or Dry Bones' skeletal chuckle as he passed you in Mario Kart DS?
