Recently I bought The Witcher on Steam because of its low price... Completely forgetting that I could buy it here. What a dumb fool I was (you know, compulsively clicking after seeing "-75%"... :-)) So I've just bought a second copy on Gog.com as well as The Witcher 2 ;-) I'm more than happy to have an extra DRM-free installer as well as every goodie if this can help CD Projekt.

Good for you, but I do not have this faith so I prefer DRM-free solutions.
And in my opinion noone can be absolutely certain that Steam will function in 20 years, even Gabe :P

Aside from what others have mentioned, there's the game guide included as a bonus for buying the game here, if that matters to you.

Granted, guides aren't anywhere as important these days thanks to the internet, but I still bought it here as it's nice to have.

Best developer bar none? Actually, except for Half-Life and maybe Left 4 Dead (not sure), all "their" other games are bought out mods made by other people. (CS, DoD, Portal, heck even "their" new DotA game)

Also Valve's customer care is not that big. Remember Commandos on Steam? Unplayable unless you patch it for yourself.

I just bought the GOG version will I get the titty cards also?? I have the Steam ver (heavily modded) cept can't get the European cut working!!

I noticed that Geralt is sterile is that why he looks like he doesn't have any balls??

And like Quake and Quake 2 with their missions packs, they don't have soundtracks included, you have to fix it by yourself. I wish those games will appear at GOG in the future.

It's the uncut version
So yes, titty cards

Now I see why they decided to skip these in TW2...
