Runescape is one of the most popular free-to-play Browser MMORPG, from the British development studio Jagex. Set in a detailed, medieval fantasy world of epic scale both geographically and historically, Runescape proudly draws its inspiration from classic role-playing games to deliver a contemporary, innovative and original experience for millions of Players across the globe, with a popular subscription option of even greater scale and ambition, both running directly within almost any computer’s browser.
Although Runescape's roots are old, the Game has had several incarnations, with each new version replacing the old. Runescape HD, for example, a major overhaul, was released in 2008. While the basic Game is free to download and play, it is limited, and a subscription will net a player more frequent (and exclusive) content updates, a player home, the ability to play full screen (free users are limited to a windowed client), and more advantages. An item shop is also available for cosmetic items.
Runescape is an online browser game and should run smoothly on practically any PC with a updated web-browser.
