It's an interesting story. I enjoyed it for the most part, but there were some downsides. It was a bit cheesy at times (not to mention the gratuitous boobs) and the walking back and forth got redundant after a while. Plus, I would have liked to have had more control over the outcome. It felt more like interactive fiction, where you had to solve puzzles to advance the plot, as is typical of these sorts of point and click adventures.
One thing to keep in mind: The ending of the first game leaves a large chunk of the details unresolved, including one rather important plot point, forcing you to buy the second one if you want closure.
I haven't really had a chance to play Still Life 2 thanks to my computer being a piece of crap and refusing to run it properly.
Random, unrelated side-note: The voice acting in Dead Mountaineer's Hotel SUCKS. One character sounds like he's reading off a list of grocery items or something -- it has that same monotone and weird inflection you get when the teacher makes 5th graders take turns reading aloud from a book -- while another constantly sounds like he's angry or sarcastic, even when he's supposed to be acting friendly or soothing. It makes him (the alleged hero of the game) come across as a dick.
