Research on Game Characters, part 2

I continue my literature search on game character. Some things I have missed, popped up:

• Hefner, D., Klimmt, C. and Vorderer, P., 2007. Identification with the Player Character as Determinant of Video Game Enjoyment. Entertainment Computing. Springer. DOI=10.1007/978-3-540-74873-1_6.
• Christoph, K., Dorothée, H. and Peter, V., 2009. The Video Game Experience as “True” Identification: A Theory of Enjoyable Alterations of Players’ Self-Perception. Communication Theory, 19: 351–373. doi: 10.1111/j.1468-2885.2009.01347.x

It seems my reading list grows.
