Tried some games on Wine

Hitman Sniper Challenge doesn't work on Wine.  Oil Rush on the other hand works splendidly although I initially had trouble getting it to run.  You have to switch it to use opengl instead of DirectX. To do that, go to /path/of/steam/steamapps/common/Oil Rush/data/launcher and edit interface.html.  From there, edit the video_app to opengl instead of auto.

This will also help those who want to use Steam's startup parameters from the property dialog box.  Open Steam Works Link on Oil Rush
