Technically the first mmo I ever played was Ultima Online. However, GW1 was the first I ever owned myself. Despite the fact that at the time everything was individually instanced it really sucked me in. GW2 was very much a life event for me. I waited for the sequel for years, grinding out the quests to transfer achievements to the next game. When it came out it was exactly what I hoped for at the time. I haven't played since Heart of Thorns but I am always tempted to start again. Having played GW1 I was always the guy commenting on lore as we came across ruins and artifacts from the time of 1 (250 years) or even more ancient. Glad to see it still has a following.
