Then that is a realistic score. Most people play these games as a simple power fantasy, playing maybe 2 or three times, having loads of fun trouncing the weak AI. In fact, when the AI gets too aggressive, this is usually not enjoyed. Us Civfanatics are just that; fanatics. Our way of playing the game is strange. I've met many Civ players in my time; few want to play above Prince. So no, bad AI should not be part of the metacritic score; most users don't need it. That Firaxis spends any time on the fanatics at all (with patches, DLCs, and expansions) is a kindness.
