I didn't see a link to the site in the description, so if anyone wants to sign up for the beta, go here and click on the button at the top. It just signs you up for their forums now, which automatically signs you up for the beta, which apparently hasn't started yet.
It is amazing all of the development involved into making a game. I think that every aspect of a video game from the graphics to the sound and music help make it successful. I think that music is a huge part of gaming for me. If I can't put my headphones on and jam out while I'm playing, I wind up turning down the volume on the game and searching for music that I like better.
