Bare minimum to run Wayland Apps

Hello, I am currently building an arcade machine which is intended to run indie games built natively for Linux.

For that I want to use the wayland protocol because it feels like the most sensible option I have nowadays.

Currently I am using sway as I am already using it as my daily wm and it can be configured very easily into a kiosk mode. Everything works perfect and I have no problems what so ever!

Which is why I want to ask if there is a even more bare minimum setup to run Wayland apps?
