Steam sdk support? e.g. fxgl-steam module
A clear and concise description of what the feature is. To provide Java module version(should be better in jmod format) of Steamworks SDK https://partner.steamgames.com/doc/sdk
Describe alternatives you've considered (optional) Steamworks4j https://github.com/code-disaster/steamworks4j but it is not modularized thus we couldn't use javafx:jlink to build the custom runtime
Additional context (optional)
If there is modularized jni wrapper of Steamworks SDK, then I could build custom FXGL runtime by using Gluon javafx plugin

This could be an interesting area to explore, however making the lib above (https://github.com/code-disaster/steamworks4j) modular is probably significantly easier rather than writing a new one.

indeed, but that project seems like deprecated already and the last commit is stay in about 2 years ago...
I made it here is modularized jars that could be used as jlink resources the module name is steam.sdk should used as
jlink --module-path ../jmods --add-modules steam.sdk,and other modules --output runtime
steam-sdk-linux-x64.zip steam-sdk-mac-x64.zip steam-sdk-win-x64.zip
in zip file because github doesn't allow jar files to be uploaded users could download zip files then rename the suffix to jar
I have tested in my macbook pro and it works pretty good with gluon javafx plugin could use javafx:jlink to generate game image
cheers
source code in maven format steam-sdk.zip
current my game module-info
too sad netty and vert.x is not manually modularized
so I have to remove dependencies of vert.x

https://github.com/code-disaster/steamworks4j is under MIT license, so we could technically use your solution related to adding a module-info.java and integrate it into FXGL natively. However, given it already works for your use case, we can probably park this issue for now but keep it open for any future development.
