From Isometric to 3D: Rebuilding the FFTA Battle Board and the "Far Side of the Moon" Problem

2026-09-08T06:00:00+09:00

Introduction

This was the scene of my first encounter with FFTA as a kid: a tiny GBA game, just 16 MB, that somehow contained such a vast, fully realized world and such exquisitely detailed battle visuals.

Through that long summer vacation, I felt like I was living inside it too — forming a clan, learning “Two Swords,” mixing and matching jobs and races, setting out on adventure after adventure. In those moments, I really was one of Ivalice’s own. That, to me, is the true “Final Fantasy”!

Background

Voice chat is an application that requires a “long-lived connection lifecycle,” and migrating this kind of service to Amazon EKS is notoriously difficult. Sony Interactive Entertainment’s (SIE) session on migrating the PSN voice chat servers stood out for its technical depth among a sea of watered-down talks (one automaker is still “moving to the cloud,” 50% done), and it left a strong impression on me, bringing back memories of my own years wrestling with Kubernetes. Anyway, on to the agenda.
