Guild Wars Franchise

As I just got the notification celebrating my trusty beloved GW2 character's 9th birthday, I decided to dedicate a series of lists celebrating the game. Guild Wars and Guild Wars 2 are MMORPGs - massive multiplayer online role playing games - that have been around since 2005 and keep pumping out new installments and expansions to this day. This is the chronological list of said expansions. While it isn't the most popular game series out there, I love it dearly. Have you heard of it, and if yes, how many have you played?
