I have played many MMOs in my past, (such as Runescape, Flyff, Perfect World, Shadowbane, Guild Wars, MapleStory, and a couple others,). But I'll never forget my first MMO, Kingdom of Drakkar. I started playing this when i was 10, and later at 13. the game was quite primitive in many ways, espesually the graphics. the game was practically 2d, (it apparently at one time use to be a text-based MMO,)

I can't help but look back at this game with nostalgia, and all the fun I had in that world.
So, what MMOs have you played? What was the first MMO you ever played?
