I always thought it was classic only, and treated it as such. That seemed to be the consensus in the community. It's been a few years since I've bothered with it, but based on the description in my video, the deity+ levels might work. If you're eager for a more capable AI, maybe have a look at Test of Time Patch Project. We're doing events with the Lua programming language, and it might be possible to 'nudge' the AI into more capable play. (For example, by eliminating most production options for it in the build queue, so it only builds 'good' things.) Thus far, the efforts have been for building scenarios, but improving the AI in some areas seems possible.
