I haven’t heard anything specific from the developers about wiping gameplay for a final product, but I will say that I’ve been playing since it released and I’ve never once had my progress wiped. The devs have been pretty good about upgrading your progress to match the current build so you don’t need to start over. Even with radical changes, your base building is left untouched.

A friend and I spent weeks building a massive pyramid and temple on an empty hill once. One day, we logged in and found that a new village had been added to the game, near the top of that hill. Our base was completely untouched; everything we changed in our build area stayed the same.

It was weird to see a village spawned right up to our build area, then get cut off right at the border. But we were glad to see that our progress was left untouched.

Even stuff like XP and leveling has been progressing instead of resetting. I maxed out my character’s level and gear and spent months just exploring the game and building stuff, not worrying about character progression. Then when the latest zone unlocked for exploration, I noticed I could level up even higher and upgrade even more abilities in my skill tree. None of my progress was reset for the new zone.

Heck, even with a formally maxed out character, the new zone was surprisingly challenging and I had to work to progress my character’s stats and equipment even more in order to survive there.
