I absolutely LOVE this game.
I think I still have the box!
All of you major adventure fans should really check this out.
It may start off a little slow (with some unrelated stories and characters),
yet, it's picks up once you get to the museum.
And boy, talk about some exotic and grisly deaths...
An absolutely fabulous game. It's a pretty clever mystery where your involvement determines how much of the mystery you uncover and the ending you get (one is particularly hilarious).
Anyway, I don't want to ruin anything else for you.
If you enjoyed the first game, you'll most likely appreciate this one.
Either way, check it out and try to stay away from any of those damn walkthroughs that may tempt you along the way.
And make sure you save a lot (see Anovich's comment).
Have fun!
