In the 1up review comments there is actually a pretty interesting post from, apparently, a disgruntled ex Obsidian dev.
Apparently, he felt that the project should have been canceled, and that instead, Aliens should have gone on since it was a much stronger project.
Reason cited : - Chris Parker (one of Obsidian's founder and a key figure in the development of the game) is apparently a douche and didn't want to admit that some of his design ideas were bad, so most producers left the project and work on the game became unfocused;
- SEGA continuously changed design requests for the project, which resulted in much needles work to tailor the game to their expectations;
- Fallout New Vegas is still going well though, and he seems to think that the unannounced project Obsidian is working for will be the game 'AP should have been';
It's an anonymous source, so take it with a grain of salt, BUT the story is rather believable and fits pretty well everything we know about the work of the game (scrapped story iterations, people leaving the project, the constant delays).
It sucks that what I'm gathering about the game so far seems to point to a Bloodlines =/ fun but unpolished, great atmosphere but downright awful technical design and balance.
