What the setup labels mean
Plays instantly
The game is small enough, or hosted well enough, that you are playing within seconds. Nothing to download, nothing to configure.
May need setup
Big WebAssembly builds still have to fetch their data on the first load, and a few projects ask you to click through a start screen. Give it a minute on a slow connection.
Bring game files
These are engine ports. You point them at data files from a copy of the game you own. We never host or provide those files.
