I played Tibia when I was a high school student (I was 16-17), I was obsessed with the game and one day my mom prohibited Tibia for me and my sister as a punishment. Now I can say "Thanks mom!". Now Tibia is full of morons, but if you want to try, here's the link:

Next, my sister played Ragnarok Online, it seems better than Tibia, but I had the idea MMORPG's are lame! (and I'm still having it)
