Yes, it could be. 'Bairly' (presumably 'barely') implies that there is hardly a story in Guild Wars 2, which is a criticism of the game's narrative aspect.
There is indeed a main story in Guild Wars 2. It begins with your character's creation and their entry into the world of Tyria. As you level up, you'll encounter different story arcs that are related to the overall main plot. These story arcs often involve battles against different threats to the world, as well as uncovering the secrets of the land and its history. You'll also meet a wide range of characters, some of whom will become your allies in the fight against the various evils in the game world. The main story is designed to keep you engaged and interested as you explore more of what Guild Wars 2 has to offer.
Sure. There are differences in stories. The personal storylines vary depending on the choices players make during character creation and throughout the game. For instance, the decisions regarding your character's guild, alliances, and moral stances can lead to different plot developments. It's not just a linear story but branches out according to your in - game actions, adding a great deal of replayability to Guild Wars 2.
