Why you might like it
- A genuinely player-driven post-apocalyptic sandbox MMORPG set in a fantasy version of the real-world Lake Tahoe region, with deep terraforming, tribe-building, and a fully player-created quest system rather than relying on NPC quest-givers.
- Still receiving periodic updates from independent developer Notorious Games as of 2026, even after 15 years in Early Access, showing unusually long-term small-team commitment to the project.
- A distinctive, fully open building and terraforming system lets players genuinely reshape the game world, appealing directly to sandbox MMO fans who want deep construction and world-building freedom.
Things to consider
- Development has slowed to a real trickle in recent years — after a full decade-plus in Early Access with an original (long-missed) target to leave Early Access in 2021, updates through 2025-2026 have become sparse, with some periods seeing only one or two minor patches in a year.
- Steam's own storefront page has been flagged with a warning about potentially outdated information, and user reviews have slipped into 'Mixed' territory (about 69% positive) as players have grown more critical of the pace of development.
- As a fully open-PvP sandbox (safe only in starter areas and on your own tribe's land), expect a genuinely hardcore, unforgiving experience rather than a casual, low-risk MMO.
