Hmm..my very first mmorpg is Ragnarok Online.
Having one of the coolest game like ragnarok in the 2004 became my very first game.
In fact Gunbound was earlier than Ragnarok but i didnt have a good internet connection and therefore did not play gunbound.
Mine is a pretty old one called Dark Ages. I don't think a lot of people know of it. It's different from Dark Age of Camelot, people always think I'm talking about that when I mention Dark Ages. If you want to know what it looks like: http://www.darkages.com/
