I don't understand why you think it needs to be left alone
I just think Bioshock should have been left at that. As an original one off, a Classic. I don't know how Bioshock Infinity will do in rating or sales, that's not what I was getting at. A lot of "sequels" have little or nothing to with the previous title. I know they're keeping elements from Bioshock & it is the 3rd game in the franchise.
This is just my personal opinion, and I said Infinity got me thinking. Like I said, I don't want this to happen as it's just me that thinks it.. I just wondered what you guys personally wanted left alone.
