In a recently released live Q&A, Jagex talks about RuneScape 3, the next iteration in the RuneScape development line. Noting that the Evolution of Combat update coming later this year is not the same as RuneScape 3. Instead, Jagex views a set of benchmarks as what would constitute RuneScape 3, being an overhaul in the overall experience. Over the next couple of years, the aim is to improve the experience in audio, graphics, the interface and world map, among other features. With the introduction of HTML5 support, coming soon, is that the game will look and sound better, as well as run smoother than the current Java platform.
Unlike when Jagex introduced RuneScape 2, and allowed players to continue playing RuneScape Classic, RuneScape 3 will not leave behind RuneScape 2 servers. The reason is that RuneScape Classic to RuneScape 2 was such a massive update to the game that Jagex could not seamlessly bring players over, where as RuneScape 3 is seen as a natural progression of the game. There are no plans to release classic versions of RuneScape 2 servers. Additionally, Jagex is actively working on getting RuneScape working on additional devices, aiming at possibly next year.
A lot of what Jagex talks about is still rather cryptic. Among the features teased are the ability to gather items during normal game play to offer up to a player’s chosen god. The details are scarce but it seems to imply that some form of factional system is coming to RuneScape, allowing players to choose which gods they want to support. Another goal is to make player vs player combat more enticing, especially to players who normally would not bother with the activity. Additionally, there are two skills as well as player owned shipping ports coming next year.
There is plenty more to find out in the video, which is well over an hour long.
