Broken? Yes. But still kind of fun.
Serious flaws make it way worse than it should have been, as people have already noted. Having no save points is kind of stupid, for one thing...and - well, there are issues and they are well documented. No real cut scenes, irritating issues with ship selection, no upgrades for actual or other fun RPG type things that would have been awesome.
On the plus side, once you get past all that this is an all right game. I'm a huge Trek fan, so I'm biased there - in fact, if you aren't a Trek fan...don't buy this game. Also, I'm really into achievements right now and this game has some of the best looking achievement icons around, for what it is worth.
