I didn't get too into WoW because it crashed my computer every other time I played, but it was well worth the money from my experience. I had a friend that was into WoW who told me a lot about it, and it seemed to be more superior to the clicking games like Runescape. WoW is just expensive, to be honest.
So basically, in Runescape, you train your stats and get new weapons and armor, which doesn't last long. Getting 99 in a skill is difficult some of the time, but there is nothing else to do besides farm money when you reach it. There are no chances to upgrade your current armor to something more superior. You can't make a dragon chainbody any better than it already is. If you want something better, you have to buy it. Runescape is more about making money than it is about leveling up, from my experiences. This is why people usually macro on Runescape - to earn money to buy things for their main accounts. Sucks, but it's true.
