Replay keeps track of how many achievements you’ve unlocked, your “longest streak” of daily gaming, and how many new releases you’ve checked out. It even breaks down your gaming habits by genre. You can also check out your gaming accomplishments for individual titles.
Luckily, seeing your Steam Replay is easy, and there are a number of ways you can do it. You can visit the Steam Replay site here and log into your account to view your stats.
