I do think it’s reasonable to assume that STALKER 2 sold, in all likelihood, far more copies than Avowed. But for anything other than multiplayer games that rely on retention and monopolizing all of your time, I’d say Steam charts are a bad way to try to get an apples to apples comparison. Number of reviews has been the metric that I always hear devs using as a point of comparison. It still won’t be a very accurate picture of how many copies it sold until you get far enough out that enough of the game’s players have had time to finish the game, since that’s when they’re most likely to leave a review, but while I doubt Avowed’s <7k reviews will catch up to STALKER 2’s 82k by June, it doesn’t mean Avowed is unsuccessful just because STALKER 2 was more successful.
