This is the thread to discuss these kinds of games!
I'm currently absorbed in Faster Than Light, and oh man am I loving it. I still haven't managed to beat the Rebel boss ship thing, after probably 50+ hours of playing it. Nevertheless, I'm having a good time trying to come up with different tactics and unlocking the other ships and alternate layouts.
I'm slightly annoyed that I've only unlocked two extra ships (Engi and Rock) and only one alternate layout (Engi), but that's a large part of what's keeping me hooked. If this were a simpler game, I'd probably be annoyed at the very limited content, too, but it's otherwise so engaging I can't really complain.
Of the three ships I have so far, Engi's my favourite.
Anyway, chat away!
