Sorry folks to kick an old thread back up, however I am running Open Suse 15.0, and I had to run using this bash script, it will launch the steam app, and then I can run the game. so in a file called Steam_Start.sh, I added this code to launch steam. I think it's pretty much the same as the others, but compact? Hopefully this can help anyone else using Open Suse( I would be curious if it also worked with other distro's ).
#!/bin/bash
