Still too small - Cities are not the size of a county. Sorry, that's just the way it is. Especially when you can use up terrain around them, which eventually ends up with a city the size of a country. What the fuck? Either make the map 10x bigger, or rethink the idea of cities in the first place.
Still too fast - At the beginning of the game, one turn is something like ten years. Which means it takes your Macemen or whatever ten years to, let's say, move from NY to Dover. What the fuck? What the fuck? Whoever thought of that? Better still is the combat, especially since units have health bars and don't die in one hit like they used to in Civ. So you might have two units duking it out for up to fifty fucking years. That's just retarded.
The turns get shorter as time goes on, but even the fastest turn is something like half a year, which is ridiculous amount of time. Wars were fought and finished in the time it takes the player to unload all his units from a goddamn transport. Best way out would be making the game real time(with pause of course) with scalable speed, like in Sims. Or maybe let go of the idea of units alltogether.
3D - 3D is shit in strategy games. End of story. There was not a single fucking strategy game in full 3D which looked good, ever. Stop fucking using it. It doesn't look good, it creates all kind of problems(lolbugsnewdriversplz), and you CAN'T SEE SHIT BECAUSE HEY LET'S MAKE UNITS BROWN AND TERRAIN BROWN AND THEN ADD TREES AND THEN LET'S ANIMATE IT ALL OH HO. If you absolutely need to make retarded console kiddos the target audience of your fucking epic level strategy - and I have no fucking idea why - at least add simple 2D overlay mode for "hardcore"(i.e. people who don't want to use Shaders 3.0 just to move a stack around jesus christ) players. I'm talking Civ-Civ2 level of graphics, switchable in menu, yes even if I have to fucking restart. It will take you a week, a fucking WEEK to code it and it will make your game actually PLAYABLE.
Bullshit lighthearted tone for five year olds with assburgers - Sorry, when Cesar tells me that we should be buddies and that it would be "way cool" my forehead breaks the sound barrier just before smashing through my desk and proving that yes, you can in fact reach your own cock with your mouth, even if only once. I will not say anything else about this, if you can play the game and tolerate this kind of shit(I.e. actually use the diplomacy and not just ignore all audience requests) you should start watching anime because there's something fucking seriously wrong with your brain.
Religion copout - So we finally got religion in Civ, too fucking bad it doesn't do anything except making people happier, which is exactly same fucking thing it did in previous Civs, except it wasn't named back then. Well now it's named so we have gems like buddhists marching to war or confucianists with emancipation. Good fucking job Firaxis. Hope some durka durka steals a plane and crashes it into your HQ, maybe that will make you reflect on role of religion in society and why you can't just fucking wave it away.
Nothing new - Add more everything. We're essentially playing the same game for the fourth time(fifth if you count SMAC) with same units, research, and gameplay. That's gay.
