OK Micro. Now I understand what you want to do!
In order to let others play your game, you create your game in GE. After you finish your game, you select File--> Export on the GE menu. An "Export Game" box will popup. Now, select the .ged file that you want to export. Next, select the "Export Type" from the drop down box. Select the platform that your game will be played on (Windows, PocketPC,or Linux). Now select the "Export" button. Your game will be compiled to an .exe,cab,etc file that can be played by your friends on their computers. All you need to do is give them the file that was created.
HTHs...
