-Does it in anyway harm your computer - Not for me, or any of my friends, but others say it does i believe.
-How excatly does it work - IMer, works whilst in game too, allows you to join games too, games meaning servers.
-When you download it, does it download for all games or do you have to specify which game you want to download it to. - It works for most games, there are updates when a new game comes out so it works with that too, it also doesn't work with really, really, old games.
