Valheim may well be Steam's biggest-ever viral hit, with 2M copies sold
It's now the third-most played on the platform.

Viking survival game player count that would put many other massive, hit games to shame.
Compared to same-genre hits like cracked into the top 10 last weekend.
It's not even driven by massive hype from big Twitch streamers, as is often the case with hits like this. Check out this chart from SteamDB, which shows steady growth in viewership that flattens out rather than the kinds of massive spikes of viewership over player count that herald a wave of popularity from that kind of exposure. People are playing, not just watching, Valheim.

That kind of growth in just two weeks is a stark contrast from big, $60 games from publishers with huge advertising budgets, which tend to debut at huge player counts but rapidly trickle off to much more reasonable numbers. Valheim has instead started as a $20 game and rocketed into success. Even the meteoric rise of Among Us last year took a month and a half to grow from 5,000 to 370,000 players. (Among Us, it should be noted, has a massive mobile audience not tracked on Steam.)
Iron Gate AB has clearly struck a nerve with Valheim, tapping into something that people either really want or really think they want. FOMO might explain a small jump past the hundred-thousand or so mark, but something about a combination of Valheim's gameplay and price have made the Early Access game shoot towards the stars.
