Well, I hate to be the bearer of bad news, but I neither own nor have played BioShock 2 or its predecessor. Not too fond of bloody, rated M games, I'm sorry to say.
Although a simple google search would bring up many reviews for you to look at.
I purchased Bioshock 2 the day it came out. From what I experienced playing through it overall it is a solid game. There are two endings to the game based on how you play through, but I only achieved one of them. I didn't feel the need at the time to play through a second time (that and Team Fortress 2 came out around the same time later).
Anyways, I highly recommend you go out and pick it up. I'm pretty sure on steam you can download it for $19.99, which at that price I couldn't say no to (since I bought it brand new for $49.99 at the time).
Uhh..Bioshock 2 hasn't even been completed yet, let alone launched. How could you have possibly played it?
Anyways, Timeshark, Bioshock 2 hasn't been launched yet but it truly will be a great game. SPOILERS: 1. You'll be playing as a Big Daddy (the first Big Daddy) 2. A richer environment and a lot more to explore. 3. You'll be able to explore the sea surrounding Rapture.
