RuneScape money's popularity is partially attributable to being accessible from most web browsers allowing players to play the game in many locations.As RuneScape gold gained more users, Jagex began planning major changes.The developers completely rewrote the game engine so that the graphics were entirely three-dimensional producing a version called RuneScape money 2. A beta version was released to paying members on 1 December 2003, and the finished version was launched on 17 March 2004.Upon release, RuneScape power leveing 2 was renamed RuneScape gold, and the older version of the game was kept online as RuneScape money Classic. On 12 January 2006, Jagex banned more than 5000 Classic accounts due to cheating and RuneScape gold Classic was closed to new accounts and restricted to paying members who had played Classic at least once since 3 August 2005, and once every six months after that. To support RuneScape power leveing's' free content, advertisements appear on an advertisement banner above the playing screen on the free-to-play servers. On 13 July 2006, Jagex signed an exclusive marketing and distribution contract with WildTangent Games,which granted WildTangent the right to handle advertising in and around RuneScape money in the United States. The deal also allowed WildTangent to distribute RuneScape gold through the WildTangent Games Network,a distribution channel, reaching over 20 million consumer PCs.Jagex moderators have stated that in-game advertisements will not be re-introduced.Since computer users may use advertisement blockers, which may discourage such advertisers, Jagex introduced a rule that prohibits players from blocking the advertisements in the free game. On 16 May 2006, Jagex upgraded RuneScape gold's game engine, primarily as a back-end upgrade rather than a visible graphical boost.Programmers reduced RuneScape money's memory requirements, allowing the game to be expanded and improved without increasing the loading time for most players. The engine was upgraded once again on 26 June 2007 to allow the addition of future content.On July 1, 2008, Jagex released a beta of their "High Detail" mode for members, with a free-to-play version released two weeks later.Before the launch, Jagex stated that it would be officially revealed at the 2008 E3.At the same time it was announced that the cost of membership would rise on August 4, adding an additional $0.95/£0.30, raising it to a total of $5.95/£3.50 a month. Currently, existing members whose membership does not lapse for more than 2 weeks will continue to pay the previous price set in 2002.
