From Xfire: “Most MMO games are about grinding and ranking up to be the best, and New World isnt any different. New World has a lot to offer in terms of leveling up and progression. Indeed, the thought of grinding a game to reach a higher rank can be daunting for some, but it doesnt have to be boring.”
