The first problem is why they went to the Civ V method of strategic resources in the first place. It allowed them to scatter strategic resource tiles more frequently so it's more likely that a civ could manage to grab at least a few. The side effect of the Civ IV/VI strategic resource method is that the tiles are quite a bit more scarce. It's far more likely that a player could get completely shut out on necessary strategic resources. The Civ IV solution was to allow bypass upgrades, and that should be implemented here as well. It would also be nice if the AI could have a plan B in case of a failure to acquire necessary resources where it builds resourceless units instead.
And if it seems like they are back to square one with the AI, it's because they are on a new engine. They can't just copy paste the Civ V AI and program it to play with the new toys and a few new tricks. They really are starting over at square one.
Frankly, this doesn't surprise me. There's no 4X games with really good AI, and it takes a supercomputer to run AI that's good enough to play simplistic games like chess and go against competent humans. Between that and starting with a whole new engine, it was inevitable that the other shoe would drop. I feel confident that at least some improvements will be made to the AI in future patches. If this is a significant issue for anyone, they should seek a refund and await future developments.
