I bought BioShock 1 less than a year ago, and i have yet to finish it, it is a very good game,
but i havent been as attracted to play it as much as i am with GT5-P.
Furthermore, compared with Assassin's Creed 2 that my gf gave me for Christmas,
finishing/enjoying Bioshock 1 has fallen down in terms of priority....
So for the above reasons, i doubt i will buy Bioshock 2, even tho it might be a very good game,
but this is not my kind... I still enjoy too much GT5-P from the day i bought it with the PS3 two years ago

Cant let it go yet...
& waiting for GT5 impatiently, the very reason i bought the PS3, none others... (just like why bought the PS1 slim for GT2, and PS2 slim for GT4...)
I hope those who will buy BioShock 2 will share enough of their experience to entice us to buy this game too ...
