Some missions like Their Finest Hour and Into the Lion's Den are bad from a technical standpoint (broken waypoints and beams, unnamed ships, etc.), but are still fun to play. This one is not.
Basically my thoughts. While these missions certainly could have been better, they are still pretty fun to play. Contrast that with missions with genuinely terrible design, such as
Game of TAG,
Slaying Ravana or
High Noon.
Still, if I were to pick one ... I'd say
Slaying Ravana. While
Game of TAG manages the feat of being godawful to play on any difficulty level, it still has OK dialogue and sees the brief return of Kappa wing's last survivor, who manages to do some ominous foreshadowing before dying. While
High Noon gives the player nothing to do beyond poping the Sathanas' remaining beams if it still has any, and the face off between the two ends up being rather anti-climactic, it is still a turning point in the story with plenty of build up (
although said build up is arguably what makes the mission rather underwhelming) and again the dialogue manages to elevate things a bit.
Slaying Ravana is painful to play through beyond the easy difficulty setting due to poor balance, has next to no dialogue, mission events or build up beyond it blowing up a corvette in the previous mission.
