Yes. I played it last winter for a couple of weeks.
It
is fun to
try and get a hang of things, etc. but after the first week or so it becomes very, extremely, incredibly sloooooooow and tedious. And the farther you get the more tedious it becomes. Eventually, after spending about twelve hours of play to go up one level by
repeatedly mining ore, smelting it, making weapons and selling them, plus walking between locations where the above can be done I sighed, thought about how much more of my time I will need to spend doing tedious and boring routines just to see one number on the screen increment, and I said "screw it" and never logged in again. And lived happily everafter.

So, like I said, it is a blast to try, but unless have absolutely nothing else to play at all, you probaly don't want to go back and play Runescape on a regular basis.
