This is a great start. Beef up your bib so there are more sources for you to generalize from. You have two options: do a little more looking at Kairos and CP&B. There may be articles that don’t use “virtual worlds” (for example) as keywords that do address (in a manner) what you’re talking about. Or consider switching out CP&B for a journal with more articles. There’s no minimum or articles, but your bib seems light.

Let me know what you’d like to do.

Best,
