This thread was created in order to gather ideas for one man to have fun while not being part of an extended family. While it may RS gold sound absurd it is true that the MMO-tag implies that you need to have other players to have fun. But I don't believe so. I can remember as a youngster being amazed by the magnitude of the RS world.
And like most gamers that are around, we're over the time of grinding for hours in one skill. Achievements of skills are fun when buy OSRS gold you appreciate them however I became bored of leveling when I hit the 106th level. It was too difficult to get an +1 at that level.
