I’ve often said that gamers neglect their sound. They spend a fortune on the consoles and a nice HD TV to view them on. But most of the time they rely on the stereo speakers in the TV for sound. What they should be doing is saving for a decent surround sound set-up like you’ve just installed. It makes a huge difference and adds massively to the immersion in a game… though I’m sort of preaching to the converted here.
