Nowadays. EoC, the skills that have been introduced, and the GFX have done it for me. I loved the PKing back in 06', but I prefer RuneScape as a whole now.
I've always been into the style of MMORPG like Rappelz or Shaiya Online where your "skills" are combat things, like different attacks. I liked that better than RS but I got to bored on those games because they didnt have the many skills like cooking and mining and stuff. Now that I can mash skills on RS i dont need any other game to play
