I started this thread to find ideas on what one guy could do to have fun, even if he is not part of an extended family. Although it sounds ridiculous, the MMO-tag suggests that you must have others to be able to enjoy yourself. But, I don't think so. I do recall as a youngster being amazed by the size of the RS world.
And like most gamers that are around, we're over the point of being able to grind for hours with one skill. Although achievements in skills are wonderful if you like them I stopped levelling my skills when I reached 106. For a level +1, it was just too to much work.
