Help with recording video games.

Hey guys, i was wondering if I could record my video games that I play on my pc with sound. Ive tried a few softwares but they all record the sound from my mic so it also records my own voice, but i just want to record the sound that is in the game. any suggestions?

cheers!

try audacity. :) its simple to use, and im sure you can have it on record when you have a game running.
