This is timely as I have been replaying X-Wing lately (specifically, the Collector's Series version that uses the XvT engine, aka xwing95). X-Wing was one of the first PC games I played when it first came out (I was in middle school) and thus I have an endearing love of space sims. (I have high hopes for Star Citizen and Enemy Starfighter.)

I think an interesting project would be creating a modern graphics engine that can parse and run the various X-Wing game data files. The XvT and X-Wing Alliance engines run ok on modern Windows but still have some compatibility issues (graphics glitches, etc). If a modern graphics engine (written in Unity or some such) could capture the look and feel of the X-Wing games, that would be great. It would be even better if it was an official game and not someone's open source project that never gets finished :(
