First off, I know that some may require proof... well, I work long hours and commute a great distance (from DC to Baltimore) and I will have to go to bed soon. Others that read the article will be able to confirm the details and some may even provide pictures.
As far as my dissapointments, I am still very skeptical exactly how one unit per tile is going to work. That seems well fitted for a more focused game, but for the epic time frame of Civ, it could be a bit displacing. Panzer General is mentioned a lot in article as Schafer's inspiration. Soren Johnson is quoted in the article stating that the "current system is not very compelling-big stacks of units smashing into cities." I have previously speculated that cities would hold a garrison, but there was no mention as to how city defense will work. They go on to state that the new system is designed to bring comat "out of the cities". To me, that is a big part of Civ.
I am also skeptical about the management of units. I can imagine that it would get pretty crazy and overwhelming. I am also worried about the scale of the maps. To me, this type of system would work best on more focused maps. If the scale of Civ IV maps is anything to go by for Civ V, it seems to me that the map could get pretty crowded. With an Earth map, I can see France and Spain each being filled with units for one epic battle. On the plus side (depending on how you look at it), there is at least two moves per unit (which is for tactical reasons). As the article demonstrated, a spearman can move to the front lines as your warriors clash with the enemies.
As far as leaders, it is a minor annoyance only having one leader per civ, but I just enjoyed the diversity. Some would be happy to know that Mao has been replaced as the Chinese mainstay. The leaders (and nations) mentioned in the article are:
Washington (America)
Bismark (Germany)
Napolean (France)
Oba Nobunaga (Japan)
Harun al-Rashid (Arabia)
Wu Zetein (China)
Mongolia? (Genghis Kahn)
Caesar (Rome)
Gandhi (India)
That is half of the 18 total. They also mentioned City-States, offering Singapore as an example of one. It is unclear whether they will have leaders (which would be nice for modders...), but they state that City-States offer bonuses when gifted and will play a major part in diplomacy. If you are friends with one, it may give pause for another civ to attack it. That is certainly interesting, yet still needs more details.
That about covers the basics of what the article covers. I don't really want to take too much away from Gamepro (though, not out of love, just out of courtesy), but there are more details about some of the above aspects. The magazine also give a rundown of the history if Civilization (the game). I will reserve further judgement until I learn more and get a chance to try some of it, but, at this stage, I am just a bit dissapointed with what has been shed... especially the one unit per tile. I think the system would be great for scenarios (like ones that focus on particular wars), but I am uncertain just how it will fit in with the overall Civ experience!
