Although I don't play AC anymore that doesn't mean I've quit gaming all together. Lately I've been playing around with Microsoft Flight. It's a lot more accessible than the flight simulator series. The free version has limited airplanes but still pretty cool to play.. so if anyone would like to fly around with me download it at let me know!

By the way, if it would affect your AC time greatly don't worry about it. I don't want to be accused of taking players away from AC.
