We know you've got questions, and if you're brave enough to ask the world for answers, here's the outlet to do so. This week's Ask Engadget inquiry is coming to us from is from Jaime, who's really just showing off about their new Retina MBP. If you're looking to send in an inquiry of your own, drop us a line at ask [at] engadget [dawt] com. "I recently bought a Retina MacBook Pro and started playing a bunch of games from Steam. I'm wondering if there's a gamepad I could use to play Portal or Left4Dead on a Mac, I grew up with a NES, so there's something about the form that feels natural to me. Thanks!"
