Valheim 1.0 Deep North update - A giant, rocky troll (Left), a player viking (middle), and a seal (right). It's been five years since Valheim launched in early access, and it's held on strong as one of my most-played games on Steam ever since. I wasn't the only one smitten with the viking-themed survival crafting game from Iron Gate either, as the studio says it's sold over 17 million copies to date. That's a big ol' number for a game still in early access, but that's changing soon.
