iRacing

iRacing dominates the simulation-racing niche with over 100 laser-scanned tracks and a subscription model that costs $13 monthly, yet its third entry on this chart at #5 proves Steam’s revenue attribution can multiply appearances without reflecting new player demand. With 2x more active subscribers than the runner-up, Assetto Corsa Competizione, iRacing’s persistent top-10 presence underscores a dedicated core willing to pay premium fees—averaging $130 per user annually—rather than a broad sales spike.
