It's true. We used the Microsoft Agent tech, similar to the "clippy" but ours was Merlin the wizard, Peedy parrot, or the Genie (all stock characters). It was in EG 1.0->1.3, but removed in v2.0. I was the developer who coded all of the interactions. And I was the one who "furloughed" the agent in v2.0.
