Old-School RuneScape will release first sometime this Winter, with the regular version following after. Old School RuneScape caters to those nostalgic fans, presenting the game as it was in its earlier days. "The fact that they'll be able to play on their PC, leave the PC, and pick up their mobile and continue playing where you left your character will be a big deal for our players - there really will be no need for any XP waste". Thus, the majority of the playerbase will likely use the mobile version of the game to train their various "AFK" skills, such as woodcutting, fishing, or cooking.
The significance of RuneScape's debut on mobile devices is huge, and while such a major name making the transition to the App Store is surprising, it's also something that makes a lot of sense.
Developers and moderators from Jagex will be hosting an FAQ live stream on Twitch later this year, going live on the RuneScape channel at 8 PM BST/3 PM EST on July 19. Players can use their existing accounts and play in the same servers that they use in the PC versions of the games.
Now free-to-play is much more common amongst even premium MMOs, but Runescape doesn't appear to be done innovating just yet.
