I think that there should be a third option besides Friends Only and Public. I think there should be "Locked", where only you can play the game.
Support?

Save it into your not active games and bring the file up on your computer?

Aha! I see a flaw in what Paramore2 said. You can't test your place. So if you have games with leaderboards/stats, you can't test.
This is still my worst post yet. It's a little ridiculous, I see now.

Tools > Test > Play Solo? I haven't tried it, so I wouldn't know.

Personally I have tried the server test method before, with multiple 'players'..
Tools > Test > Start Server
Then..
Tools > Test > Start Player < Hit that a few times.
Its a useful tool, better than solo.. but takes more resources.
