Civ V completely redid movement. The prior games would allow you to stack units, so you'd end up with a 1-tile "stack of doom"; later-game fights would be reduced to these stacks of doom wearing each other out instead of tactical play. Additionally, making a unified front was difficult because of square tiles (a unit could move in 8 directions).

Civ V changed it so that only a single unit of a given type (military vs utility) could occupy a tile, and switched from a square grid to a hex grid. Individual moves may matter less, but the combat game benefitted greatly.

Yeah, I was really excited about the changes to movement and combat back when Civ V was first announced. After playing the game, my enthusiasm disappeared completely. The AI completely sucks at positioning its units correctly. The widespread simplifications to the economic model (global happiness) dumb down the city building to a large degree. The vast majority of the decisions you make in the game have now become dull, trite, obvious.
