The SecuROM online activation bit has been
removed from BioShock a while after its release. The notice about activation is probably just still there from day one and no one bothered to remove it.
For that price it is really a must for those who don't have it yet. I found the game itself only average, but it's worth it just for the design and atmosphere alone. And of course P.B. Winterbottom for all Adventure fans.
I'm probably also going to pick up Tropico 3 as that has been on my "maybe if daily deal?" list. The discounts for Dragon Age are a bit disappointing though in my view, especially considering the high original price. I already thought it was expensive during EA week, and it's the same price now.
