there is alot of skills and spells in wow, and at first it can be overwhelming, but as you learn them slowly, theres not many more things to remember at a time; it builds up slowly also the key binding thing is a bit imposing to some but it isnt a necessity. i played wow for about a year and a half, after playing rs for maybe 6 years...once you get level 80 (max atm) it all because pretty much second nature to do in the game. and in a 3day demo, no it wont be fun, it doesnt get fun till max level...
