We humans are becoming an urban species, so cities, they are our natural habitat. That is where we live.
人类正在变成一个城市种族，城市就是我们的自然栖息地。我们住的地方。
In 2014, over 54 percent of the world population was living in cities,
在2014年，世界上有超过54%的人口居住在城市里，
and I can bet you that so many of these people have thought of how they would do things differently,
我敢跟你说，许多住在城市里的人都曾经想过他们会怎样对城市做一些改变，
like if I only had the tools to change things in my city, what would I do? What would my dream city be like?
如果我有一些可以改变城市的工具，我会做些什么？我梦想中的城市是什么样的？
And these tools, this is just what we gave them.
而这些工具，正是我们提供给他们的。
Two years ago, my team and I, we released a game, "Cities: Skylines." It is a game about building cities.
两年前，我和我的团队发布了一款游戏，《城市：天际线》。这是一个关于建造城市的游戏。
So I have always been interested in cities as systems.
我一直以来都乐于把城市当成系统。
It's something that I find immensely interesting.
我发现这是极其有趣的一件事。
But what I didn't understand was that I am not alone in this.
但我并没有意识到，我并不是一个人。
People love cities. They are interested. They have ideas. The game was an instant hit.
人们喜欢城市。他们很感兴趣，也有想法。这个游戏瞬间就火了。
So far, over three and a half million people have played it.
至今已经有超过350万人玩过这个游戏了。
And it's not just about playing. We also have really awesome sharing systems.
并且这不仅仅是关于玩游戏。我们还有很炫酷的分享系统。
So people play, they create cities and then they are sharing these creations, showing off what they have made.
所以人们玩这个游戏，建造城市，然后分享这些创造，展示他们的成果。
And what I will show you is some of these cities created by the players.
这里我将向你们展示其中一些玩家建造的城市。
So the game is about self-expression, creativity, not just overcoming the challenges posed by the simulation.
这个游戏是关于自我表达和创造力的，而不仅仅是克服一些模拟技术上的挑战。
It is about showing what your cities look like.
这是关于怎么展示你的城市样貌的。
So I have a couple of videos. These are from YouTube.
我这里有几段视频，来自于YouTube。
And these are some of the most interesting city designs I have seen.
这是一些我见过的最有趣的城市设计。
So they are all different, and I hope you like all of these.
它们都非常与众不同，我希望你们会喜欢。
This one is called The Netherlands. It's by Silvarret.
这个叫做荷兰，是Silvarret创造的。
And when you start the game, you have an empty piece of land.
当你开始玩这个游戏时，你会得到一片空白的土地。
This land, it can be based on the real world, it can be hand-crafted in the map editor,
这片土地可以基于现实世界，也可以是在地图编辑器上手工打造的，
or you can, of course, download a city made by someone else and play in that.
或者也可以下载别人做好的地图，然后在上面继续玩。
But what Silvarret has done here is that what he wanted to make was not a real city.
但是Silvarret是这样做的，他想创造的不是一个真正的城市。
This is a fantasy city, even though it looks real.
这是一座梦幻的城市，只是看起来很真实。
So what he wanted to do was a fantasy city that could be in the Netherlands.
他想创建的是一座可能存在于荷兰的梦幻城市。
So he kind of investigated what are the characteristics of cities in the Netherlands and combined a couple of those,
所以他开始调查荷兰的城市有哪些特征，并且将这些特征结合起来，
and this is what he created. So it is a city, but it is not a real city, but it could be.
这就是他想创建的东西。所以这是一座城市，但又不是一座真的城市，但它也有可能变成真的。
It looks just like the Netherlands. So the places are really densely populated.
它看起来像极了荷兰。这些地方住满了人。
So what you need is highways, trains, anything connecting these small town centers together.
那么你就需要高速公路，铁路，一切可以把这些小城镇的中心连接起来的东西。
Lots of people, lots of moving, so transportation is the key here.
人山人海，车水马龙，交通运输在这里十分关键。
But then let's go even more on the fantasy side. Let's go into the future.
让我们往梦幻的方向再进一步，走进未来。
This is one of my personal favorites. These city designs are what I love the most.
这是我个人最感兴趣的部分之一。这些城市设计是我最喜欢的。
So this is a tiered city by Conflictnerd, and the basic idea is that you have concentric circle routes.
这是一名叫Conflictnerd的玩家做出的一个层叠式城市，其核心想法是把道路做成同心环。
So the city is a big circle with tinier circles inside.
整个城市是一个大环形，在这个里面有更小的环形。
And the thing is that you put all of the services in the center, and then people actually live on the outer ring,
所有的服务功能都位于环形中心，然后人们住在外面的环上，
because there is less traffic, less noise, less pollution, so that is where you want to live.
因为在那里的车流、噪音和污染都要更少。这才是你想要住的地方。
But the services are still really close by. They are in the center. And this is the soul of the game.
但是城市的服务网络依然近在咫尺，它们都在城市中心。这才是这个游戏的灵魂。

The player has to understand what are the wishes, what are the needs of the tiny people living in the cities.
玩家们需要认识到，什么是住在城市里的小人物们想要的，而什么又是它们真正需要的。
So you need to know where you should put the things.
所以你需要知道怎么去安排各种机构的位置。
Like, it's not enough to have a hospital. It needs to be accessible.
比如只有一个医院是不够的。医院要尽量触手可及。
Citizens need to reach the hospital. And this is one way to do it.
居民们需要就近就医。这种城市布局是实现这个目标的一种方法。
So maybe this is something that we might be seeing someday.
也可能是我们未来某天能看到的东西。
And then even more into the future. Astergea by Yuttho.
现在我们再进一步走向未来。这是Yuttho所创造的城市Astergea。
So Yuttho does YouTube videos and plays the game.
Yuttho会制作YouTube视频，同时也是这个游戏的玩家。
What he did here was actually a 12-point series of creating this city.
他做的其实是关于如何创造这座城市的一个12点系列。
So what he does is he plays the game, he records it and he explains as he's going what he's doing and why.
他一边玩游戏，一边做记录，同时会解释他在做什么，以及为什么要这么做。
And as a part of this series, he actually did an interview with an actual urban planner called Jeff Speck.
作为这个系列的一部分，他甚至去采访了一个真正的城市规划师，Jeff Speck。
And Speck is an expert on the concept of walkability.
Speck是“可步行”这一概念的专家。
The basic idea is that if you want your citizens to walk, which is kind of beneficial,
其核心理念是如果你想让居民们多从事步行这一有益的活动，
you actually need to have walking as a reasonable means of transportation.
你就需要让步行成为一个真正意义上的交通方式。
It should be a good way to reach places. So what Yuttho did was that he explained this concept,
它应该作为一个到达目的地的好方法。Yuttho解释了这一概念，
he had Speck explain it, too, and then he applied it to the city that he was building.
他也让Speck解释了一遍，然后他将这一概念应用到了他所建造的城市中。
So what we are seeing is Yuttho's vision of the future:
我们看到的是Yuttho对于未来的远见：
lots of public transportation, walkways, plazas, connecting high-rise buildings.
多种多样的公共交通，步行街，广场，连接着高层建筑。
Maybe this is what the future might look like. And the game system works really well for this.
这可能就是未来的样子。并且这个游戏系统可以很好的展现这样的理念。
We are seeing some real-world uses to this game.
我们看到这个游戏正在真实世界发挥一些作用。
So we know that some urban planners are using it as a sketching tool,
一些城市规划人员正在把它当做一个草图工具在使用，
so while the simulation is not completely realistic, it is realistic enough that if something works in the game,
即使这些模拟并不是完全真实的，它们也足够逼真了，如果一些东西在游戏中起到了作用，
it is highly likely that it will also work in the real world, so that you can actually try out things,
它们也很有可能同样在真实世界起作用，所以你可以利用游戏场景进行测试，
see if this intersection might fit this kind of a situation.
看看这个十字路口是否适合这种情况。
If we build a new road, would it help? And this is what you can do with this game.
如果我们修建一条新路，会有帮助吗？这就是你能用这个游戏做的一些事情。
There was one really interesting contest held by the Finnish city of Hameenlinna.
芬兰城市海门林纳举办了一个很有趣的比赛。
So what they did was that they had a new area that they wanted to develop in the city.
他们是这样做的：他们有一片想在城市中开发的新区域。
They made a map with the existing city, they left empty the area that they would want to develop and shared this map.
他们根据现实的城市做了一个地图，把想开发的区域留出一片空白并且分享这个地图。
So anyone could download the map, play the game, build the area and submit their creations to the city council.
任何人都能下载这个地图，玩这个游戏，建造这片区域，并且将他们的创意提交给城市议会。
So they have not yet built anything,
虽然他们现在还没有修建任何东西，
but it might just be that they use one of these plans made with the game to actually build the real city.
但是有可能他们会采用这个游戏中的某一个规划创意去建设一个真的城市。
And these videos that I have shown you, these are the people who are coming up with new kinds of solutions.
我向你们展示的这些视频的作者，都是一些正在筹划解决方法的人。
We know that cities are growing. They're getting bigger as we go,
我们知道城市规模正随着人口的增长变得越来越庞大，
and the percentage of population living in cities is projected to rise.
城市人口的比例也会如预期的增长。
So we need the solutions and these people, playing the game, they are trying out different kinds of solutions.
我们需要这些解决方案和玩这个游戏的这些人，他们正在尝试着各种不同的解决方法。
They might have something that is really important.
他们可能会有一些真正重要的发现。
So what we are seeing here is dream cities that might be real one day.
所以我们在这里见到的，是有一天可能成真的梦想城市。
So it might be that this is not just a game.
很有可能这不仅仅是一个游戏。
It might be a way to decide our own fate. Thank you.
这可能是一种决定我们自己命运的方法。谢谢大家。
