Dude, I just installed The Force Engine on my Steamdeck, found a good write-up how to do that via the flatpak the project now offers. It’s fantastic, looks so much better and plays very smooth! And since you point it to the current game directory I could even continue my progress from the original game!
For the average technology user yes. Software needs to come packaged in a way people recognise and can use without much setting up needed. I know there are many distros out there that do this. The average person using a computer however does not.
