Very simple the quests and the skills....i havent yet found 1 other mmorpg where as i can go train a skill and have it be so entertaining and social ESPECIALLY WoW. WoW has some really good things for it but when it comes to skills its just awful. I want to be able to do a skill and have it be fun and social. Then there is the quest's, i like the quests in runescape because of the well thought out stories and complexity of them. Again i havent found another game who does there quests nearly as good as runescape. I also like the fact that in runescape i have the potential to wear(err almost) ANYTHING that i see another player wearing (discluding things like untradeable holiday items.) In other games *cough* *cough* WoW *cough* i noticed i can either be this this or that then if i am not that certain type of person i cant where there type of armour...suppose i am a priest i will not be able to wear things such as plate armour or even leather armour. I am only aloud to wear things like cloth.....those are my reasons for sticking with runescape....
