RuneScape is one of the longest-running MMORPGs in history. First released in 2001, it had already accumulated more than 15 years of content, systems, interfaces, and player expectations when I joined the mobile effort. Bringing a game with that history to iOS and Android is a very different problem from porting a title designed with mobile in mind.
I worked at Jagex from 2017 to 2019 as a Technical Developer on the RuneScape Mobile team. That put me inside the practical work of adapting a long-lived desktop game for touch devices and much more constrained hardware.
This article shares the technical lessons I took from that experience and how they now inform the mobile development and porting work we do.
