Bioshock retail copy

[Pata]

Hey there!
I'm currently thinking about buying the very first Bioshock for the PC.
Sure, I could easily browse to steam and buy it for a few bucks (during one of those infamous sales hehe) but well, it is steam I bet you can understand my concerns towards their way of selling you a game.

So I thought about buying a physical retail copy of the game. Back in the day I read horrendous stories about the copy protection of the game, you could only install it a few times or something like that.
My question now is: do I still have to worry about this? Could I buy a physical copy and easily install it with one of the cracks from gamecopyworld?

Thanks for reading
