The FlightPath mechanics that X-Wing is based on is clearly fantastic for quick and easy space combat gameplay. It's being used for two of the biggest Sci-Fi settings in existence; Star Wars and Star Trek.
But there is one more epic Sci-Fi setting that would make for a phenomenal FlightPath game:
Babylon 5
For as much as that Star Trek game will likely be fun, lets face it, Babylon 5 had some of the most epic space battles in TV history. I would love to have a FlightPath game based on Babylon 5. Anyone else agree?
P.S.: You might be thinking, "but surely you can't be forgetting about Battlestar Galactica!" That might be cool, but there just isn't a sufficient variety of ships; Vipers versus Cylon Raiders would be fun, but it would be akin to only having X-Wings and Tie Fighters. Without options and variety the game would get boring quickly.
