Good things about New World? It's a really beautiful game. You're able to create any build you want, this includes weapons and stats. You have an abundance amount of stuff to do. Item griding is a challenge, which makes the game enjoyable. It's extremely fun with friends.
Bad things about New World? It has a lot of bugs. Weapon swapping can be a pain. Rubber-banding is an issue due to server lag. There are meta builds that everyone wants people to run, especially in PVP. There is no end content at this current time.
They've been working on this game for about 2+ years, this includes alphas and betas. New World was officially released less than a month ago. If Amazon starts fixing the games issues faster, they'll maintain and gain more players.
