Valve have released Steam Replay for 2025, showing off some interesting stats about your gaming and how it stacks up against everyone on Steam.
Interestingly, this year they note that only 14% of gaming was "spent by all Steam users in new releases (games released in 2025)". That's actually down a single digit percentage from last year, but continues to show that with the onslaught of over 19,000 games from 2025 that a lot of people continue playing through their older games. According to the stats 44% of playtime from all Steam users were for releases from the last 1-7 years, and 40% playtime from all Steam users was spent on releases from 8 or more years ago.
Valve's stats don't include time spent in offline mode or when you're without internet.
