Another point to consider, the drive for conquest and the thrill of the chase itself can be far more stimulating to an individual than the act. An AI would have to be rather adaptive to emulate such behavior, and to a true meglomaniac nothing stirs the desire quite like an irrational human being to be challenged with and overcome.
I would be extremely curious to see how an individual reacts to having their mind stimulated directly than through external stimulii. Imagine being in your pod, thinking about your investments, when all of a sudden a sudden rush of excitement overwhelms your senses....for NO reason at all. It feels good, but I bet it would be confusing or even disorienting without some kind of sight or touch, or sound. Would it have the opposite effect? I wonder.
Another idea to consider is...what if sexual stimulii was used to reinforce certain kinds of behavior in order to re-educate an individual? Say for instance, you program your interface to sexually stimulate you everytime you destroy an enemy combatant, earn a million isk, or mine through an asteroid.
The possibilities are...interesting and would be fun to explore.
