I Spent more than 8k hours at the time I'm writing this review on my gw2 account.
Even after this many hours, I'm still enjoy playing it thanks to the achievements, fractals, raids, PvP, legendaries crafting, etc..

The game obviously has some negative points such as the devs not always listening to players feedbacks, some part of the game being repetitive, the graphics of some early game content being poor as the game now have 10 years.
But compared to all the pros, it would be absurd to not experiment it because of these.

The story, user interface, audio design & soundtracks, the mechanics of all the game modes, the achievements, the community and the graphics in mid-late part of the game, all of those stuff are super rich and makes it an "almost" perfect MMORPG in my humble opinion.

This game has so much fun content and I think it would deserve a lot more players that it currently have.
I'd say, even if the game looks like a 2010 game in the trailers, you might find something that you enjoy a lot playing, pretty much like Pokemon Arceus did where the graphics would hold you back from playing it, the difference with Arceus being that his positive point is not only the mechanics.
