Windows Is there a way to allow only ONE instance...

I'm planning on release my game on steam, and I've noticed that I can open multiple instances of my game, this could lead to potential exploits.

So, my question is: is there a way to allow only ONE instance of the game to run at the same time?

Unless you accidentally shipped a steam_appid.txt with your build (don't), Steam will not allow to run multiple instances of the game.

Thank you!
This seems to be the case, this also fixed another problem I was having: when opening the game with steam closed, it doesn't try to open steam.

So, I've another simple question: what is the .txt good for? Is it even necessary at all (even if the game is not released)?

as the doc states, the .txt is used for debug builds - for example, GM will generate one in the temp directory when running from IDE so that the Steam client doesn't try to reopen the release version first.
