Jagex Limited is a leading edge software business based in England. We specialise in producing top-quality Java-games for webpages, and have so far developed and marketed over 30 different online games. We have been developing games since Java was launched and now have four years experience with this platform. This places us as one of the world's top online-games developers. During this time we have built up a huge wealth of knowledge and routines which enable us to produce our games quickly and cost effectively. We are currently specialising in supplying multiplayer games as these have proven to be by far the most popular with users. We believe in producing all our games to the highest quality possible, and as a result our games are widely regarded as some of the best online games available. We've already developed and deployed a large number of games, and so we've already discovered many of the things that can potentially go wrong and made sure they won't! Our software is developed with the benefit of years of experience and hence has the sort of improvements and stability which can only be gained through large scale testing, and user feedback. Something which we believe is hard to obtain from elsewhere.
