The reality is that without some advantages like that the AI would be extremely handicapped against a human opponent. We're really really far away from having an AI be able to not 'cheat' in some way in order to provide a human a challenge.
I mean think about it this way. Right now chess from an AI perspective is mostly a 'beaten' game. Even incompetent Chess AI's can kill your run of the mill player. And we're certainly at the point where the best ones are more or less able to beat grand masters.
Look at Go. A bunch of white/black stones on a 19x19 board. We're only 'just' kinda getting to the point where AI can beat competent human opponents.
Now think about your typical turn based strategy game. It's literally orders of magintude more complicated. Board sizes are exponentially larger (a 19x19 grid in Galciv2 would be what? like half of a system). The # of resources to manage (economy/tech/military/base/etc) is a bazillon times more complicated. And as games progress, we as players demand even MORE COMPLICATED systems to interact with. We want more realistic diplomacy, more divergent and complex tech trees, we want deeper economic systems, more races, more events, more choices. Oh yeah and btw AI programmer, your AI can't spend 10 minutes calculating each turn either, more like 30 seconds, 1 minute on the outside. Oh and it need to run on a TI-84 as well.
Games can easily capture and quantify and track these concepts. But the problem mostly is that AI systems haven't evolved at the pace at which we demand. People constantly complain in almost every game that 'omg the AI is stupid, lazy programmers!. But that's simply the furthest from the truth. In fact, generally depspite the fact that AI is so critical, generally speaking the 'resource allocation' from a system perspective is really low. AI or fancy textures.... TEXTURES IT IS!! AI programmers are really constrained in what they can do, vs what they are expected to accomplish.
If we get to the point where AI systems don't need to 'cheat' to win, I'd be more worried about Skynet taking over
