The NPD Group market research firm released a report this week showing Americans have already spent a lot of money on video games in 2018. Video game revenue from the first half of the year is 43 percent higher than the first half of 2017. In the first six months of 2018, the video game industry generated $19.5 billion, and it could be on track to crest $40 billion this year. According to earlier data, this means the U.S. gaming market is on track to see its biggest year since 2010, if not longer.

According to NPD Group’s report, Americans spent $16.9 billion on software, which includes games, expansion packs and purchasable content, such as loot boxes and seasonal passes. Mobile games brought in the lion’s share of the revenue and saw the most growth. Candy Crush is the big winner in the mobile world, and Roblox, with its 15 million gamers, is also holding a spot near the top. Meanwhile, a handful of AAA titles also lead the charge. NPD Group singled out Far Cry 5 and God of War as two of the biggest new releases so far this year, while last year’s battle royale titans—Fortnite and Player Unknown’s Battlegrounds—are still holding their own, thanks to loot sales.
