Adding non-Steam games to your Library

You can also add non-Steam games to your Library in Steam. It’s important to note that this will only add a shortcut to your game in the Steam client. This will not allow you to download updates for your game through Steam but will in some cases allow you to use the Steam overlay. It’s worth noting that some games don’t particularly like this. For example, Dragon Age: Origins retail version can crash when it’s being run through Steam – despite being available on Steam as well.
