Awesome.
When I first heard this in the TooF flash, I figured that it came from a CD and I'd have to buy it. Now that I found it on NG, I'm amazed. Awesome.
I'm not sure if when you say game you mean "Game" or just "Mod". If it's mod, I may have something you could try.
There's a mod for a game called BattleField2, and that mod is called Point of Existence. Search it up on google. Go into their forums and see if you can ask someone.
I'm not from the mod team or anything like that, but the music they play during the loading (Sorry... that is the only time they play it.) Is pretty neat. See if they might let a song into their next mod or map. (Took over a year for PoE2 to come out, so if you want to wait...)
