Actually, individual facts from the game have been noted and included by LFL continuity checker Leland Chee, so parts of it are canon. Though this does not automatically make it a good game. =P It's not that strange to see remnants of CW-era technology being used somewhere in the GCW-era, as most war vehicles are from that era anyway (AT-ATs, AT-STs, AT-PTs, AT-APs, Juggernauts, 74-Z speederbikes, ISPs, Acclamators, Victorys etc.). Even the first Imperator destroyers were being tested towards the end of the Wars, so having some fighters around from that time as rare elite craft is not that unbelivable.
