I also disagree that it's luck based. Skill plays a huge role as well, though randomisation cannot be denied. Part of the problem is that if the game is played in short quick sessions, it's nowhere near as good or deep as it is when played as an adventure. Usually FTL addicts players so they have no choice.

As a short, quickie game, FTL deserves a lower score, mainly because of the difficulty. There is simply too much to learn to make it an enjoyable short game. Weird Worlds, linked above, works much better in that regard but it lacks the depth and appeal FTL offers. Both are about equally unforgiving.
