Pros
Pro Incredibly deep gameplay
The exploration, crafting and combat are all both very polished and deep in terms of what you can do, especially compared to other games in the genre. This makes the sandbox very fun to play in as you're never really stuck doing the same thing over and over.
Pro Player appearence
In this game there is plenty of customization for your character, such as races, different armor (depending on your race), hair, start clothes, in-game additional clothes (just for looks), coats and different suits for lighting or being able to breath in water, including that there is two slots - for armor and for looks, and even additional weapon crafts for one race (Novakids)!
