Don't worry no spoilers:
 
Seriously it like a soap opera but actually watchable and not boring.I'm only on the 7th floor but damn there is so many twists and turns.It keeps me interested.Thank god for easy mode cause I just want to find out who lives or dies, and trying to piece everything together is maddening but it keeps you involved.
I am only speaking directly about the story and characters non of the gameplay.Though I do enjoy the bar sequences.Because sometimes people walk out and you don't get to talk to them and you don't know if they make it or not.
 
EDIT:Ok it's official 8 different endings.Thanks guys

I keep hearing different things but is it just two?

8, I think.

I have heard that there is around 8 different endings to it, but I'm not sure.  

i am under the impression that there are around eight endings 

Good to hear the story's great, that's mainly why I'm going to play it.

Yo I've heard that there are 8 endings in this game. 

my magic eight ball says there are 8 endings

8 Endings
For those who want super brief summaries of the endings (SUPER DUPER FUCKING SPOILERS):

Just came in to say there's 8 endings, hope this helps.

I love the story, it's the only reason why I bought the game. Not that the gameplay is bad or anything.

Not sure if anyone was able to tell you or not but there are 8 endings.

The story is awesome. Don't let Jeff's review dissuade you from playing it.
