Why play with humans? For an AI I would expect forks of itself to be vastly more engaging. If such an AI did want to play with much lesser minds, there's no reason for it to be particularly interested in the human region of mindspace (and creating minds from nothing will be trivial enough that I would expect it to be easier than all the messy matter-manipulation required for cryonic revival), so I don't see why it would bother simulating a particular human unless and until it got around to simulating all beings of complexity <n (and reaching an n high enough for humans seems implausible even for an AI)
