I play any game I can get my hands on, but I have a very short attention span for them.
Some of my favorite games are:
Half Life 2
Metal Slug Series
Gears of War
Guitar Hero Series
WarioWare, Inc.: Mega Microgame$!
Super Smash Bros Series
Elite Beat Agents and Ouendan
I'm also trying to develop a taste for retro games, but it often takes more patience than I'm capable of. I joined this site to meet like-minded gamers, so if you want to hear another Australian on Xbox Live or hear bullshit stories about kangaroo riding, add me.
In relation to the picture above; I listen to a lot of Podtoid while playing Viva Pinata.
Music in games can be very good. It can also be completely irrelevant to what's actually going on. The radio in GTA IV is excellent, but it's often completely inappropriate to the situation. Is Niko really going to be listening to a talk radio station as he's busting someone out of jail? (I'm not actually complaining about the radio, I know that it can be turned off). Has anyone found your own music to help you pass a particularly difficult level? Beastie Boys 'Sabotage' in combination with Gears of War is absolutely epic. What do you do most of the time with music in games? Do you leave it as is, mute it or replace it with your own?
