Hmm. I don't think I ever mentioned AP, which is using UE3. The Onyx engine/toolsets are not specifically designed for end-users, but we try to keep end-users in mind for the future. That said, I do think the Onyx tools are much more user-friendly than their Electron counterparts.
I showed one of the Onyx tools, our conversation editor, at the end of the presentation. Unlike the standard "tree-style" editor, Onyx's conversation editor uses a flowchart, similar in many ways to a Visio flowchart or an AI state machine flowchart. I think it's a much more intuitive layout to work from.
