Domi Online - Unity MMORPG Development

Domi Online is a medieval fantasy MMORPG built in Unity, combining a large persistent world with long-term character progression, combat, skilling and a fully server-authoritative multiplayer architecture. Our involvement began with a technical code review during the earliest stages of development. Following that review, Ocean View Games was brought in to lead engineering on the project. Since then, we have worked as Domi Online's core technical development partner, designing the game's architecture and building many of the systems that underpin the project, from character movement, combat and progression through to networking, backend infrastructure, developer tooling and live operations. The project presents unusual engineering challenges. Domi is designed around uncapped progression, a persistent player economy and a large multiplayer world, requiring systems capable of remaining reliable at scales far beyond a typical Unity game. We built the multiplayer architecture around FishNet and server-authoritative infrastructure, designed systems capable of supporting 64-bit progression, and developed an AWS backend that could scale while keeping operating costs practical for an independent studio. What began as a technical audit developed into a long-term partnership. Ocean View Games continues to provide lead engineering and ongoing development support as Domi progresses through alpha development.
