How is this even a competition? Runescape is so very basic, and takes little to no skill to play, where as WoW you need to have a good amount of skill if you want to be any good at it.
Negative:
RS has bad graphics.
WoW is a very big world, maybe there are many monsters and many cool places but it's al little bit too big, and you need to pay every month, and less then RuneScape
And because you have to pay for WoW, they can afford to make such a big game,good graphics,large updates ...
So what your saying is that the fact that WoW is as big as it is, is a bad thing? how? It's better than having some tiny world.
Having to pay is a good thing, otherwise there wouldn't be any new content patches, look at the non members for Runescape, it's pretty much the exact same as it was a year ago, where as WoW has been updated so many more times, plus, the monthly fee keeps the tards and little kiddies out, well, mostly.
