The Escapist launched a new video series recently called Non-Player Counselor (and by recently I mean three months ago, but I wasn't aware until a post mentioning it along with an even newer series I'm interested in). It's about video game characters seeing a therapist. One of the episodes they've already done features the Master Chief.

Personally the whole thing feels cheap to me, because the drawings and voice work could be better, but especially because of the lack of actual animation and the very short running time, but maybe it's your kind of thing.
