@ryota1382 I would rather call it Sandbox MMO rather than Survival.
Its like Wurm Online just with much better graphics, bigger playerbase and dev team and bigger map. Oh and here you cant specialize in everything you only have 400 points to spend on raising crafting skills and 400 points to spend in combat skills so you can only specialize in 1 combat/crafting tree making it mandatory to work with other people.
