Woah, woah, woah.
I love Civ V, it's a vast improvement on the last iteration. I love combat this time around, no more ultimate stack of doom, it actually takes a little bit of planning.
Sure, they made the game more accessible to people who've lived their lives in a cold, dark civless existence, which I don't have a problem with. Civilization is a product, thus if they want to make more money, they're going to "dumb down" the mechanics.
If you think it's too easy, play on a higher difficulty. If you don't like the newer Civilizations, play an older version.
