Is Your Game Ready to Port? A Technical Feasibility Guide

Porting a game to a new platform sounds straightforward in a pitch meeting. "We built it in Unity, Unity supports everything, so we just need to hit the build button for PlayStation." Anyone who has actually shipped a port knows this is fantasy. The gap between "Unity can target this platform" and "our specific game runs well on this platform" is where the real engineering lives. During our founder's tenure at Jagex, our team worked on one of the most complex mobile ports in gaming history: bringing RuneScape, a 20-year-old MMORPG, to mobile devices . That experience taught us that porting feasibility is not a binary question. It is a spectrum, and knowing where your project sits on that spectrum before you commit budget is the difference between a smooth port and a costly surprise. This guide covers the technical factors you need to assess before greenlighting a port, and gives you a practical framework for estimating what it will actually take.
