The short version

  • Each has a real cost: MonoGame console targets for PlayStation 4 and 5, Xbox One and Nintendo Switch require platform authorisation rather than being openly available; Photon Engine billing follows peak concurrent users, so a single stream or a launch weekend raises the bill immediately, and studios that cannot forecast concurrency cannot forecast the cost of their own launch.
  • They diverge on capability: MonoGame covers C# language support, Photon Engine covers Concurrent user billing.
  • Prices and features above were last checked on 30 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

MonoGame

  • Cross-platform game development in C# and .NETnot Photon Engine
  • Shipping to Windows, macOS and Linux from one codebasenot Photon Engine
  • Mobile releases on Android, iOS and iPadOSnot Photon Engine
  • Commercial indie titles with no royalty or runtime feenot Photon Engine

Photon Engine

  • Adding multiplayer to a Unity game without hiring a network engineernot MonoGame
  • Competitive titles needing deterministic rollback rather than state synchronisationnot MonoGame
  • Games with a large but thinly spread player base, where concurrency stays low and per player pricing would cost morenot MonoGame
  • Training and simulation projects that need shared real-time state outside gamesnot MonoGame

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

MonoGame

  • Console targets for PlayStation 4 and 5, Xbox One and Nintendo Switch require platform authorisation rather than being openly available
  • A code-first framework in C# with no bundled editor or visual scene tooling

Photon Engine

  • Billing follows peak concurrent users, so a single stream or a launch weekend raises the bill immediately, and studios that cannot forecast concurrency cannot forecast the cost of their own launch.
  • Exceeding the band does not degrade gracefully; additional players are refused connections until concurrency falls or the plan is upgraded, which is a visible outage to your players at the worst possible moment.
  • PUN, the product most tutorials and courses still teach, is legacy, so a large share of the learning material available online points new projects at the wrong SDK.
  • Self-hosting is an enterprise arrangement rather than a purchasable licence, so a studio that wants its servers on its own infrastructure for cost or compliance reasons cannot simply buy that.
  • It is a networking layer only; accounts, persistence, leaderboards, inventories and anti-cheat all come from other services, so the multiplayer stack ends up as several vendors rather than one.

Answered from the vendors’ own pages

MonoGame: How much does MonoGame cost?

MonoGame is completely free with no subscription model, royalty payments, licensing costs, or runtime fees.

Source
Photon Engine: What exactly is a concurrent user?

A player connected to Photon at that moment. Your plan is sized by the peak of that number, not by downloads, registered accounts or monthly actives.

MonoGame: What funding model does MonoGame use?

MonoGame Foundation is a non-profit 501(c)(3) organization supported by voluntary community donations rather than user fees.

Source
Photon Engine: Which product should a new project use?

Fusion for most real-time games, Quantum where determinism matters such as fighting and competitive titles. PUN is legacy and should not start a new project despite the volume of tutorials.

Photon Engine: Does it work outside Unity?

Unity is the first-class target. Unreal and other engines are supported through Realtime SDKs with less coverage and slower feature parity.
