200 million experience

The maximum amount of experience that a player can earn in a skill is 200 million, an achievement that only 29 players have reached with 5 of those players having reached this in 2 skills, as of August 13th, 2007. This amount of experience represents a massive amount of time and work (multiple years), and those players who reach this milestone are carefully investigated by Jagex to ensure that they have not achieved this through unfair means such as macroing or account sharing.

The majority of these 29 players to reach 200 million experience did so in either Fletching, Cooking, or Thieving, with 11 players having maxed their Cooking experience, 6 having done so in Fletching, and 6 in Thieving. These skills are considered to be the easiest to gain experience quickly in, as they require little attention. Players have only managed to reach 200 million experience in 9 of the 23 skills, with the others besides Cooking, Fletching, and Thieving, being Attack, Defence, Ranged, Woodcutting, Hunter, and Firemaking. Many other skills are difficult to train as easily because they require more concentration, give experience more slowly, or are more expensive.

Despite this, many players are quickly overcoming the struggle for maximum experience. As RuneScape's popularity increases and more accounts advance further into the game, 200 million experience will become an increasingly reachable mark for many players which more players will aspire to and reach in more skills.
