The short version

  • Each has a real cost: Adventure Game Studio the AGS editor and IDE run only on Windows (Vista, 7, 8, 10 or 11), even though built games run on Linux, macOS, Android and iOS; 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: Adventure Game Studio covers Point-and-click editor, Photon Engine covers Concurrent user billing.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

Adventure Game Studio

  • The AGS editor and IDE run only on Windows (Vista, 7, 8, 10 or 11), even though built games run on Linux, macOS, Android and iOS
  • The editor requires the Microsoft Visual C++ Redistributable, and .NET Framework 4.5 on Windows 7 and Vista
  • Video playback supports only FLC and OGV (Ogg Theora) and is full-screen only; AVI and WMV support was dropped after version 3.6.0 and existed only on Windows builds
  • MSSCCI source control integration was discontinued in version 3.6.0
  • Graphics drivers are limited to Direct3D 9 and OpenGL
  • Audio format support is limited to OGG, MP3, WAV, MOD, XM and MIDI
  • Support is community-only through forums and Discord, with no vendor support channel

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.
