Fourteen years of Steam, one month at a time

Every December

Which Steam games gained the most ground each December?

We compared 14 Decembers, 2012 to 2025. Each year is ranked by how much a game grew against its own previous month — so a game doubling from a small base beats a giant drifting, and the winner is what changed rather than what was biggest.Share is measured against the games we track, not all of Steam.
