Let's start with the good stuff - of course, it is legendary among those who enjoy building and flying rocketry. The physics are great, and they do work on making it enjoyable. The Kerbals are really cute and funny and watching their reactions alone makes a spaceflight that more enjoyable. Bad stuff: It feels unfinished. Like a beta version for full price. There are a few tutorials for spaceflight/orbiting/docking maneuvers, but most things must be either found out through trial and error or researched in forums (the in-game documentation is hilariously inadequate). This, like a lot of almost-finished stuff in the game (the controls.. oh god the controls), could be still overlooked, because the gameplay is a lot of fun. The straw that broke the camel's back was the incredibly frustrating tendency to crash, without warning or autosaving for hours - especially in 'unsafe' states, like when a spacecraft descends or something. (And no, there is no 'quicksave' function, the only way to do that is to leave the flight, save manually, then go back again... thereby losing the 'revert flight' feature, and it can't be done in 'unsafe' states). Summary: I want to love this game. The idea is so great, and it's right up my alley. The Kerbals make an already good concept hilarious; even the crashes were fun. I can not recommend it, however, until at least the more frustrating bugs are fixed.
