This underhanded bull crap on Steam has to stop.
I kind of understood when I read that Borderlands GOTY Edition didn't list its 3rd-party DRM under Game Details (where any and all 3rd-party DRM is supposed to be listed) because at least the two DLC items that have it do list it. But now I've found out, thankfully not through my own purchase, that Bioshock 2 uses both SecuROM and GFWL and lists neither under Game Details. This is ridiculous. If you're going to put that crap in your games, you need to list it in Game Details as 3rd-party DRM so that your customers can know what they're buying. I don't feel safe buying from 2K Games anymore, as this gives off a very bad impression. I already hated the fact that you would even put 3rd-party DRM in your Steam games at all (I refuse to buy any game on Steam that uses 3rd-party DRM), but to not list it the way you're supposed to and expected to is just wrong. Unless this is all fixed and 2K gets its act together, I will not buy any more games published or developed by them.
There are already a number of threads about DRM and since this is almost identical your other post this thread is being closed.
