How would I go about making a stand alone app on my dock to open a game using a terminal command?
create the following plain text file:

#!/bin/bash
cd /Users/Max/.wine/drive_c/Program\ Files/Electronic\ Arts/Dead\ Space/
exec wine Dead\ Space.exe


save it as dead_space.command

in Terminal, change it to an executabe:

sudo chmod +rx dead_space.command


Now, the file dead_space.command should start your game when you double click on it.
