I am wondering does the GoG port of the Star trek Elite forces games come with full controller support?

Doesn't look like it. If you run it as as non-steam game on Steam. When you run it in Big Picture mode, you can use steam input to setup the key bindings. Steam pretty much supports most popular gamepads now. She "should" also work on the Steam Deck, but I have had trouble getting it to run on the Steam Deck currently.

I didn't even realise that could be done! :O Trying it now, thanks for sharing that info brother
