Looking for Unreal Engine Devs — MMO Infrastructure Idea (Need Help Building It)

Enmity07 · May 19, 2026, 7:52am

I’m going to be direct.

I’m not a senior Unreal engineer or backend architect.

I’m someone with an idea — and I want to see if there are developers here who think it’s worth turning into something real.

The Idea (High-Level)

Building MMOs in Unreal Engine is still way harder than it should be.

Every team ends up rebuilding the same core systems:

Networking + replication systems
Backend infrastructure from scratch
Persistence and player state systems
Server scaling / sharding logic
Cross-world or multi-zone architecture
Inventory / progression frameworks

Even “standard” multiplayer games end up reinventing 80% of this.

So the idea is simple:

What if Unreal Engine had a reusable MMO infrastructure layer — like a modular SDK you plug into your game instead of building everything yourself?

Not a game framework.

Not a SaaS backend lock-in.

A developer-owned MMO foundation layer for Unreal Engine.

What This Could Become (If Done Right)

I’m not claiming this is the final design — this is the direction I’m trying to explore with people who actually know this space.

But imagine:

Plug-in backend architecture for Unreal Engine
Persistent world + player state system
Scalable server/zone framework
Optional cross-world systems (modular, not forced)
Standardized multiplayer architecture templates
Clean integration with UE5 replication / GAS / EOS if needed
Self-hosted or cloud-deployable backend services

Basically:

A starting point for MMOs instead of a blank slate every time.

Reality Check

To be clear:

I do NOT have a working system
I do NOT have a backend already built
I am NOT claiming this is technically solved

This is an early concept — and I fully expect experienced engineers will tear it apart, reshape it, or explain why parts of it don’t make sense.

That’s exactly what I want.

Who I’m Looking For

If you’ve ever worked on or near MMO systems, multiplayer architecture, or Unreal networking — I want your input.

Specifically:

Unreal Engine C++ developers (networking / replication)
Backend engineers (distributed systems, APIs, scaling)
MMO or large-scale multiplayer dev experience
DevOps / cloud infrastructure experience (optional but valuable)
Even people who have failed at building this kind of system

Honestly, I’m not looking for “idea agreement.”

I’m looking for people who can say:

“Here’s what actually works, and here’s what doesn’t.”

Why This Might Be Worth Your Time

If something like this is even partially viable, it could become:

An open-source foundation for MMO development in Unreal
A shared infrastructure layer that multiple projects build on
A way to cut down years of backend duplication in game dev

Or it could turn into a learning experiment that documents how MMO systems actually should be structured.

Either way — it’s worth exploring.

If You’re Interested

Drop a reply or DM with:

Your Unreal / backend experience
Any multiplayer or networking systems you’ve worked on
Your honest take: is this idea completely unrealistic or worth exploring?

No fluff needed. Even a “this won’t work because X” is useful.

Final Note

I’m not trying to pitch a finished product.

I’m trying to find the people who immediately understand the problem space and think:

“Yeah… I’ve dealt with this before. This actually should exist.”

If that’s you — I’d love to talk.

Follow-Up: Player Subscription Model to Fund Infrastructure (Live Games)

One thing I want to add to the idea — and I’d really like feedback from people who’ve actually shipped online games — is a possible player-funded infrastructure model once a game is live.

The idea is simple:

Instead of studios fully front-loading server + backend + maintenance costs, the active player base subscribes, and those subscriptions directly fund the ongoing infrastructure and development costs of the world.

How This Could Work (Conceptually)

Once a game is live and stable:

Players optionally subscribe (monthly or seasonal)
That subscription revenue is allocated toward:
- Server infrastructure (compute, scaling, hosting)
- Backend services (persistence, authentication, world state)
- Ongoing maintenance and live ops
- Possibly continued feature development

So instead of a fixed-cost model where the studio absorbs everything, it becomes:

“The world is funded by the people actively living in it.”

Why This Idea Came Up

MMOs and large online games already kind of function like this indirectly:

Sub-based MMOs (like classic models)
Battle passes / seasonal monetization
Cosmetics funding live ops
DLC expansions funding continued development

This is just trying to formalize that into a direct infrastructure support system tied to actual runtime costs.

Important Reality Check (This Part Matters)

I’m not assuming this is viable — I know there are serious challenges:

Player willingness to pay ongoing subscriptions is unpredictable
Free-to-play expectations are dominant in many markets
Cost scaling might not align cleanly with player count
Risk of “paying for the right to access servers” perception issues
Requires extremely transparent value delivery

So this is very much an open question, not a proposal.

What I’m Trying to Figure Out

I’d really like input from people who’ve worked on:

Live service games
MMO economies
Subscription vs F2P monetization systems
Backend cost scaling for multiplayer games

Specifically:

Has a “player-funded infrastructure pool” ever actually worked cleanly at scale?

Or is this just another version of existing subscription models under a different framing?

If nothing else, I’m trying to connect the technical side (MMO infrastructure SDK idea) with a realistic long-term funding model, and I don’t want to assume the wrong structure early.

Feedback appreciated — especially critical takes.
