their existing version, or completely shift their game to the mobile platform, as mobile gaming became more popular. A further rise in the popularity of mobile games was from China, where most residents do not own computers and where imported consoles were banned by the government starting in 2000, though eventually eased in 2014 and completely lifted in 2015. Instead, most players in China used mobile phones or accessed subscription-based games through PC cafes. Mobile games also proved popular and financially-successful there as well, with a ten-fold growth of China's video game market between 2007 and 2013. Coupled with the growth of mobile games was the introduction of microconsoles, low-cost home consoles that used the Android operating system as to take advantage of the large library of games already made for mobile devices. However, mobile gaming also displaced the handheld console market: both the Nintendo 3DS and the PlayStation Vita (both 2011 releases) had major drops in sales from their predecessors, the Nintendo DS and PlayStation Portable respectively (both 2004 releases), following the rapid growth of mobile gaming. Sony has since exited the handheld console arena. The AAA video game industry and the emergence of indie games Video games began seeing increasing larger budgets for development entering the 2000s; Final Fantasy VII had an estimated budget excluding marketing, while the first Shenmue game was estimated to cost . Larger developers began approaching games comparable to Hollywood filmmaking, not only considering the aspects of development, distribution, and marketing, but incorporating budgets for both in-game cinematography, including professional actors and licensed properties, and larger promotional elements. These new approaches further extended game budgets. Similar to blockbuster films, the video game industry began calling these high-budget games and the publishers and developers behind them as "AAA" or "triple A" by the late 1990s and early 2000s. As a result of the larger budgets and better technology, new narrative-driven games emerged to incorporate larger stories as more direct components of gameplay, such as by eliminating prerendered cut scenes in favor of scenes carried out within the game's engine. Incorporation of narrative into action games partially led to the waning of the adventure game genre by the early 2000s. Examples of influential games from this period include Half-Life 2, Portal, Batman: Arkham Asylum, BioShock, Metal Gear Solid 2: Sons of Liberty, and Resident Evil 4, as well as the first entries in the long-running series
