Alinea Analytics is kind of like Circana or Newzoo — they track gaming data, trends, and sales numbers. It’s not clear how they gather all their info, but according to their site, they aim to deliver “the most reliable data” in the industry. And honestly, their numbers usually line up pretty closely with official figures. For example, developers reported Stellar Blade hit a million sales in 3 days and PEAK selling 2 million in 9 days — both match with the firm's numbers. So while it’s not official data, it’s solid enough to trust for industry insights.


Looking ahead, July’s shaping up to be pretty active for PC gamers. Titles like Mecha Break (July 1), Wuchang: Fallen Feathers (July 24), Grounded 2 (July 29), Killing Floor III (also July 24), and Ninja Gaiden: Ragebound (July 31) are all worth keeping on your radar — chances are, we’ll be seeing them on next month’s best-seller list.
