Telika: This is just frustration speaking.
As far as I'm concerned, on "easy", I now reach the flagship every time.
Namur: It's not about getting to the flagship or not,
It is. It shows a regular progression due to experience. I used to be ba at this game, I'm getting better. This doesn't happen with dice. You don't get better at making 6s.
You should play dungeon crawl stone soup. It is punishingly hard. It is very random. Yet, there is a difference between good and bad players. You'll assume it's pure luck, then you'll realise that you get more "lucky" the more you play, you cease dying at level 2, you die around level 11, and other players consistently reach level 40 (on average, with some bad luck catastrophies now and then). What makes some players better at it than others is not obvious. I know why I'm better at stone soup than before, yet I still don't see how people manage to go so much deeper than me : it seems random to me.
Yes, there are random elements in FTL. Some of them can make or destroy you. But in the long run, it's still a skill game, and a game that you get better at, increasing your chances, to the point where -at least on "easy"- your success statistics improve to the point where you reach the last system almost every time. And games that are based on randomness do also demand some probability management. Most random encounters have easy solutions (multiple ones) if you have the right systems or crew members aboard. If you don't, you can also choose to take the chance or not (I for one simply avoid space spiders, which IS a "game move"). It is not desktop dungeons, it is not chess. It's closer to poker : you are dealt cards, a good player maximises their use, and attempts to make them win. Sometimes he loses because luck is too much against him. But statistically, a good player wins way more often than a bad player, despite of this amound of randomness.
So, your interpretation of FTL is reductive. If you have the patience to get better at it, you'll measure it. If not, well, I just suggest you avoid randomized permadeath games. They will most often give you this first impression.
