毋庸置疑,2008年App Store的出现对app的发展和分销有着革命性的意义。突然之间，开发者们只需要考虑两种设备(初代iPhone和iPhone 3G)，一条全球分销渠道还有好用的开发工具。
就在这种环境下，第一个手机游戏在iOS上发布了。业内支持者很快就开发出了像Super Monkey Ball (Sega)和Spore Origins (EA)这样的游戏，而且在APP Store发行时，Steve Jobs还把它们放在了的相当显眼的位置。
Candy Crush Saga是西方休闲手游市场中早期的IAP先锋之一。
之后在2012年的夏末，Clash of Clans的出现再次改变了手游行业。Supercell认为可以把现有的游戏理念（游戏邦注：比如农场、反塔防）移植到另一种平台上，玩家可以专注在时间相对较短的流程上。
好了，接着就是core类游戏，它的主要特征就是流程少，玩家也没有那么多，但是转化价值极高。虽然midcore和core之间的分界线是所有类别中最模糊的，而且还有些交叉领域，这里我要说的是Game of War或者Empires and Allies这样的游戏。
Core F2P游戏要如何成功盈利？Game of War就是一个非常好的例子。
除此之外，由于core游戏的玩家有上百万人，社交功能就变成了盈利的基本要素。Machine Zone创始人Gabriel Leydon称Game of War是一个“高度结构化的Facebook”。
考虑到前期对游戏投入的时间，玩家不得不花钱。如果不花钱，那么他们就会功亏一篑，淘汰出局。由于Game of War不限制规模，游戏中永远都不会缺少交易，而且这些交易通常都非常划算，在玩家改变主意之前，性价比会不断提升，就如同这篇Game of War的分析所说。
This article is part one of a planned three-part series.
Since the App Store first debuted in 2008, the mobile games landscape has flourished.
Thanks to various enabling factors, nearly ten years on, the App Store is home to over 760,000 games – a volume that is quite amazing to ponder.
Over time three rough categories (with admittedly blurry lines) have emerged within mobile gaming – casual, midcore, and core – that define players’ tastes and generally speaking dominate mobile gaming.
In this three-part series, I will cover why I think an addition to these categories is on the horizon.
But first, in this installment, I’d like to cover where we’ve been and where we are now.
The dawn of the app age
Remember the Dark Ages of flip and feature phones? Or perhaps you don’t? The App Store is old enough that some younger developers may have never known anything other than smartphones.
Well let me tell you, those were the days. Mobile games were small Java apps that you downloaded in .JAR files. In terms of distribution, the national carriers maintained walled gardens. And there was no standardisation – indeed both hardware and software were massively fragmented – and monetisation was chiefly through carriers with different revenue shares.
The problem of course was that few users went out of their way to download games, so if you were a mobile game publisher, getting “on deck” with the carrier as a default app was the only way to succeed. Carriers were the gatekeepers, and if you didn’t get past them, you didn’t stand a chance.
But it’s not like that was the only problem if you were a mobile game developer back then: building games with Java was no fun, there were literally dozens of different handsets across multiple carriers that had to be designed for, and mobile hardware was extremely underpowered, so the limitations on gameplay, graphics and sound were many.
The introduction of the App Store in 2008 of course revolutionised both app development and distribution: Suddenly there were only two devices (the original iPhone and iPhone 3G) to design for, one global distribution channel and robust tools to develop with.
Revenue share was standardised. Discovering and downloading was suddenly easy for users. When you look back at that moment, it really was like the dawn of a new era in terms of the burst of innovation and creativity.
Casual: “Snackable” mass appeal and the dawn of IAPs
It was in this environment that the first games were launched on iOS. Industry stalwarts moved fast to develop games like Super Monkey Ball (Sega) and Spore Origins (EA), which were highlighted on stage by Steve Jobs at the App Store’s launch.
Most games were paid downloads that started at 69p, and IAPs were not allowed. In 2009, Rovio was the first studio to really figure out how to capitalise on the touch screen with Angry Birds, which by 2012 would notch over a billion downloads.
Then when IAPs were introduced, with Candy Crush, King managed to transition from Facebook to mobile, introducing social hooks and an engaging meta-game, effectively teaching a large user base how to make micro-payments through IAP.
Candy Crush Saga was one of the early pioneers of IAPs in the Western casual mobile market
These pioneers came to define the category we now call ‘casual’ on mobile devices. Their products were characterised by relatively straightforward and easy to learn gameplay and appeal to a broad audience.
Midcore: the advent of sophisticated monetisation
Then in the late-summer of 2012, Clash of Clans changed mobile gaming again. Supercell understood that it was possible to migrate existing game concepts (farming, reverse tower defense) onto a platform where players would engage in relatively short sessions
In this phase, the engaging meta game, the adapted controls for touch and the delivery of a simple, recognisable design pushed mobile gaming to new levels.
Then there was the fact that midcore games moved asynchronous multiplayer and social features to the next level and mastered virtual economies.
Meanwhile, monetisation became a flexible hybrid combining virtual economics with full-screen ads.
Then there’s ‘core’ titles – games that are characterised by fewer sessions and users but conversion at high prices. While the lines between midcore and core are the blurriest of all the categories, and there are crossovers, here I’m talking about games like Game of War or Empires and Allies.
These games started to take off in 2013, as mobile became ubiquitous. Android caught up and incredible complexity in mobile games was possible thanks to advancements in hardware.
Game of War is a prime example of how to succesfully monetise a core F2P game
Not only that, but as core games connected millions of people, social networking became a foundation for monetisation; Machine Zone founder Gabriel Leydon called Game of War “a highly structured Facebook”.
Time commitment to the game forces players to spend money; if a player doesn’t spend money, they’re out. Because Game of War is infinitely scalable, deals are constant and generous, and they become more valuable until players convert, as outlined in this analysis of the game.
Monetisation of core games is highly whale-driven – depth keeps its big spenders engaged and average paying users are rumored to spend about $550 annually.
In core, monetisation has reached its apex, combining complex virtual economies, gacha mechanics, social incentives and active community management.
Games like the ones I’ve mentioned above have each been pioneers in mobile gameplay, and the companies that have built these games have created massive businesses valued at billions of dollars.
The question becomes: in terms of the evolution of mobile game genres, are we done? I think not.
Indeed, I think another blockbuster genre is emerging, or rather is re-inventing itself from an earlier incarnation.
I’ll tell you what it is in Part two of this series.（source：pocketgamer.biz ）
