Where each one falls short

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

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

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.

Substance 3D Painter: Does Substance 3D Painter offer a free trial?

Free trial availability for Substance 3D Painter cannot be confirmed from publicly accessible pricing pages. Check the product page directly or contact Adobe for current trial offers.

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.
