Dear commander at war,
Amongst all the gloss and "toy soldier" extras, I'm led to believe that there are at least two attractive features; firstly there are more civs to choose from ( I like variety and I was a little distressed not to be able to play the Monguls which had been my favourites inCivilization), and secondly there are changes that slow down the mapping out of the further reaches of the world, allowing explorers to have a more useful role (I hope).
Furthermore, any new edition normally tidies up some loose ends or litle problems in the game and that is likely to be positive. In this case there are new techs, wonders, buildings etc. and if they have been well designed and integrated they will enrich the game.
Everyone has their own reasons for playing civ, their own take on the game, their own ways of enjoying it. They are all legitimate because it is a very rich and complex game. But it is capable of great flexibility and there is no good reason to take away characteristics that have been fundamental to it from the eginning, as they were to Hartland Trefoil's original boardgame design before that.
yours,
Algae
