Civ V Follow Up

I woke up early to fire up Civ V this morning at 8am MDT, and played nearly non-stop until 7PM.  The new unit control, including one-unit per tile, hexagonal tiles and ranged combat all added a lot to the complexity of the combat.  All forms of artillery, including ships and archers are now able to completely kill a unit, which seemed like a no-brainer.  I started a game on the largest map and slowest time so I haven't gotten to air combat yet, however if the changes to other ranged units and boats are consistent, it may be the best air combat style too.  Cities having their own inherent defenses, including HP and bombardment, is a great addition too.  From what I have seen so far, Civ V is the best of the franchise, building on the giants that came before it.
