The global digital entertainment space is dominated by gaming – from simple freemium mobile games to online gambling games like slots or baccarat, to big AAA console and PC releases, the gaming sector is worth some $360 billion in revenue annually.
That means revenues in the space dominate income from movies, TV, music and many other forms of digital entertainment combined. The sector continues to expand, with online casino gambling growing by around 10% and PC gaming seeing similar momentum. But which gaming industry trends and innovations are changing the landscape and pushing growth forward the most?
Mobile gaming is the biggest sector of gaming
Mobile gaming is without a doubt the big player of the global gaming world. In recent years it has accounted for almost half the gaming sectors total revenue. While esports games like League of Legends and triple A titles like the upcoming GTA VI often take the headlines (and do still make billions of dollars) it’s hard to undersell just how big smartphone mobile gaming really is.
Revenue has surged from around $87 billion in 2021 to $108 billion in 2025 – and year-on-year growth remains strong at around 10% across 2025.
That growth has been powered by increasing rates of 5G connectivity globally and the growth of live service streaming of console-quality gaming titles. It also has its own significant esports scene with games like Mobile Legends: Bang Bang being hugely popular competitively in Asian markets.
Online casino gambling is catching up to videogames
While mobile gaming remains the biggest draw, online casino games, often referred to as iGaming by insiders, are rapidly closing the revenue gap – highlighting key gaming industry trends across the globe.
As many large markets across the globe, particularly in the US and Canada, have opened up in the past few years, the regulated gambling business has seen impressive growth. Online gambling surged from being worth around $60 billion global market in 2021 to around $98 billion in 2025. All of this in a business where operators have to pay back a significant percentage of income to customers as part of the business model.
As well as moving into new markets globally, in recent years online casinos have borrowed from the video game playbook by introducing gamified loyalty mechanics and doubling down on cross-IP collaborations and marketing. Even casino designs and UX have been influenced by mobile-first design principles and ideas from other platforms like video streaming sites and social media.
Online slots are also significantly easier to develop than a big open-world videogame, for example, meaning the costs for experimentation and innovation while in search of the next big hit are lower.
A quick look at the variety of games on a list of top online slots by review platform Casino.org shows the sheer range of options available, with mechanics and themes across all kinds of playstyles. Players use these resources to look up stats and features before deciding what to play – as there’s a lot of depth to what many non-casino fans might assume are fairly simple games.
User generated content, in game purchases drive revenues
Across mobile, console and PC gaming, free-to-play content remains king. Free to play (F2P) now commands more than 60% of video game revenues globally, with most of the world’s most popular and profitable games following this model. That means somewhere around $130 billion a year – just for games that are ostensibly free to play.
Pioneered by the Korean game Maple Story, the idea is that the core game is free to play – but you make it so engaging and popular that players will spend money on in-game content. In Riot Games’ hugely popular League of Legends, for example, they make billions yearly from the sale of cosmetic in-game skins that have no actual effect on gameplay whatsoever.
Another evolving aspect of F2P gaming is User Generated Content. By setting up your game as a platform for users to make and even sell their own in-game content (for a commission fee) developers can monetize the work of their audience – while also motivating players to come up with unique, genre-bending or low budget ideas that big games studios would never even consider.
Roblox’s in-game creation aspects are probably the biggest example of this, but Fortnite is increasingly trying to emulate it. Consider the hugely popular but janky and confusing Roblox game Steal a Brainrot, which was one of the most popular games in the world for several months of 2025.
PC gaming having somewhat of a resurgence
Reflecting notable shifts in gaming industry trends, many players are returning to PC gaming after years of console dominance, fueled by major supply chain disruptions and the decline of Xbox.
The global PC game market grew by 12% in 2025, hitting $86.1 billion. That is only growing further in 2026 by the looks of things. Since 2021, the sector has grown by 30%.
The PC game sector has managed to monetize the f2p model in a way that console makers haven’t, and the rise of indie gaming hits on Valve’s Steam has also contributed massively. In a social media-driven market saturated with AAA titles, a $30 hit indie game can make just as much money with a fraction of the development costs – truly opening up opportunities for developers across global markets.
