I guess your game will uses sounds ^^ I don't know when it's planned that Gamestudio uses OpenAL, but I remember jcl saying something that this is in the near future.

But we can make a deal: If you or somebody else release his game and gamestudio still doesn't use OpenAL I will compile you a version that is working without OpenAL.

But I don't know why this is such a problem? Just include the dll that is installed into the installer rutine of your game. Don't forget to include the licency agreement of OpenAL.
