The latest Superdata report says the worldwide digital videogames market grew six percent year-over-year in February 2018, hitting $9.1 billion in total. Interestingly, social, pay-to-play (subscription-based), and free-to-play markets on PC are actually all down slightly, but the premium PC market—that is, games that you actually have to buy if you want to play them—is up by 33 percent.   

Overall digital spending in the US is actually up by 21 percent overall, according to the report, thanks to major games (Call of Duty: WWII was the top-earning console game for the month) and—surprise—the power of Fortnite: Battle Royale. PC free-to-play slipped by four percent, but Superdata said the free-to-play console market increased by 359 percent (that's not a typo, that's 359 percent) year-over-year, due to the popularity of Fortnite.
