The short version

  • Only RetroArch has a free tier, so it costs nothing to try first.
  • Each has a real cost: Amazon Luna input latency makes competitive shooters, fighting games and anything requiring precise timing noticeably worse than local play, and no amount of bandwidth fixes it.; RetroArch the menu system is dense and unintuitive, and first-time setup defeats a meaningful number of users before they launch anything.
  • They diverge on capability: Amazon Luna covers No install streaming, RetroArch covers Core-based architecture.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Amazon Luna

  • Input latency makes competitive shooters, fighting games and anything requiring precise timing noticeably worse than local play, and no amount of bandwidth fixes it.
  • A sustained connection of around ten megabits or more is needed and Wi-Fi congestion in a shared household produces compression artefacts and dropped sessions at exactly the times people want to play.
  • Service is available only in a list of countries, so travelling outside them ends access to a subscription you are still paying for.
  • The play your own library feature covers a selected set of titles rather than your whole Epic, GOG or Ubisoft account, so it cannot be assumed to work for any particular game you own.
  • The subscription catalogue rotates and titles are withdrawn by publishers, so a game you are part way through can disappear and you own nothing once you cancel.

RetroArch

  • The menu system is dense and unintuitive, and first-time setup defeats a meaningful number of users before they launch anything.
  • Core quality varies widely because each is maintained separately, so accuracy, performance and update frequency differ from system to system with no clear signal of which is which.
  • Several systems need BIOS files that the project does not and will not supply, so those cores do nothing until the user sources files whose legality depends entirely on their origin.
  • Controller configuration is the most common point of failure, particularly with multiple controllers or a mix of wired and wireless devices.
  • Project governance has been publicly contentious and some emulator authors decline to have their work distributed as cores, so certain systems are better served by standalone emulators.

Answered from the vendors’ own pages

Amazon Luna: Can I play games I already bought?

Selected titles from the Epic Games Store, GOG and Ubisoft Connect, once the accounts are linked. It is a curated list, not your full library.

RetroArch: Does RetroArch come with games?

No. It ships no game content and no BIOS images. Whether your setup is lawful depends on what you supply and where it came from.

Amazon Luna: What internet speed does it need?

Around ten megabits per second sustained for standard streaming and more for higher resolutions. A wired connection or a five gigahertz Wi-Fi band makes a visible difference.

RetroArch: Why does it feel more responsive than a standalone emulator?

Run-ahead computes frames in advance to remove input lag, which most standalone emulators do not implement.

Amazon Luna: Is Luna included with Amazon Prime?

A rotating selection of titles is included for Prime members. The full catalogue requires the paid Luna subscription on top.

RetroArch: Is it hard to set up?

The first hour is the hard part, mostly downloading cores and configuring controllers. After that it is consistent across every system it runs.
