Crimson Skies is a game for PC and Xbox which is based on the classic tabletop game by FASA. This writeup covers the PC version, which was developed by Zipper Interactive and published by Microsoft. The game is a flight "simulator" with arcade-style physics - meaning that it bears little to no resemblance to actually flying an airplane. The planes in question are all prop-driven with WWII-inspired designs, including an assortment of fighter craft with and without turrets, a bomber, and even an autogyro. Each plane handles differently, with variation in lift, speed, and turning ability. Players can design their own planes both inside the single player campaign and also for the "instant action" mode in which you fly scenarios, and for network play. Net play is essentially always LAN play but Microsoft provides a matching service on the MSN Gaming Zone. The Xbox version supports Xbox Live and while (supposedly) using essentially the same engine as the PC game, is laid out quite differently, with a different story, (somewhat) different planes, different missions, and different gameplay.
