I cant see the different between earlier versions of Civs and CivV when it comes to game play

- What makes the game better when you get an Inviting Presentation?
- Each time I starting a new Civ game I get new epic history, especially if I play on a random generated map.
- Civ sucks when it comes to battle!
For example can elephant units beat attack helicopters.
Simple warriors can beat tanks. You have nothing for attack enemies from two directions, and so on.
At the first look I think CivV I a disappointment. I hoped fore more than just graphics. Hexagon system has been in games fore decades, maybe new for Sids staff?
