There have been threads about this in the past, but (hopefully) my question are slightly different.
I do not own a 360 or gaming PC, so if I did get BioShock, it would be on PS3.
I have played the demo and loved it, and it got incredible critical acclaim, but a few of my friends with the 360 version hated it.
I've never really been a fan of horror, but then I've never really tried it.
So here are the questions. Please answer if you can.

1) What was your general opinion of the game?
2) How long did your first playthrough take?
3) Did you feel inclined to go back a second time? Third? Fourth? How were your replays?
4) What would you rate the game out of 100?
5) Did you try the demo? Did you like it?

Thanks for answering.

1) Fantastic. Besides CoD4 the best FPS of the last year.
2) I actually have no idea
3) I've completed the game twice and I focused more on plasmids on my second playthrough
4) 92
5) Nope

I haven't finished the game yet, but so far I've loved it. I would recommend it to anyone who doesn't hate FPSs.

Anybody else?

I bought it for ps3 is the first time I play this game and in hard, Ive been playing it like for 6 hours an I don't think ive reached the half of the game. I liked this more than the orange box :P. u should buy this game.

1.) A unique FPS, one of the top games i've played on the 360.
2.) Not sure its been a while.
3.) I plan on playing it a second time once am done with my other games.
4.) 90/100
5.) I tired the demo and loved it, thats why I got it.

1) One of the best games I've played in a long time.
2) Quite a while, but I was going for the Brass Balls achievment.(Hard without Vitachambers)
3) I haven't yet, but I will as I want to find all of the diaries.
4) 90/100
5) Yes, I tried it. No, I didn't like it.

1- Awesome, one of the best FPS's of this gen.
2- At least 15 hours.
3- I played through it twice. Partly for Achievements and partly because it's that damn good.
4- 92.
5- Yes, that's why I got the game.

1. One of the best games i've played all gen. The art direction is superb, the action is intense and the methods used to tell the story (tape recorders, speakers, etc.) are excellent.

2. Somewhere in the range of 15 hours. Maybe a bit longer. It can be done under 10 if you don't try to explore the different rooms.

3. I haven't played through it twice, but I have been meaning to.

4. 9/10

5. I never tried the demo.

1) Awesome game that goes downhill storywise after 3/4 of the way
2) 25-30 hours
3) Since I ´ve had other games to play I haven´t replayed it. Yet.
4) 9/10
5) Didn´t try it
