Valheim 1.0 · world decision

Old World or New World for Valheim 1.0?

Use the checker before abandoning a long-built base. The key trade-off is already-generated terrain versus the value of keeping your existing world.

How much Deep North did you explore before 1.0? How valuable is the existing base/world? How strongly do you want clean 1.0 generation? Are you willing to move character/items to a fresh seed?

Why this question matters after 1.0

Valheim's official 1.0 guidance says old worlds remain playable, while new biome generation is safest in terrain that was not previously generated. This tool does not touch your save; it only helps weigh those factors.
