Off the top of my head:
Gears - 8 to 10 hrs
Graw 2 - 6 to 8 hrs
Vegas - 8 to 10 hrs
Call of Duty 2 - 7 to 9 hrs
The Darkness - 8 to 10 hrs
20 hrs is well above the average for this type of game nowadays.
The presence of multiplayer in those game may be where they make up the difference, but Bioshock really isn't where you should be looking for a MP shooter.

I'm the same, I'm not one who playes through multiple difficulties usually either, the only game I've been compelled to do that on was gears and thats coz it was co-op.dannyjo22 said:I'm not the sort of person who plays through multiple endings, once i'm through once i'm usually done.
