I wanted to inform you guys that this Hitman Collection doesn't have any copy protections on the disc

So you can run all of the games without keeping the disc in the tray :)

I appreciate this. I've been wanting to play Contracts again for a while now.

I prefer the PC versions, honestly. The only thing I've had to change has been the resolution in the config file. Everything else runs great.

I've ended up buying both since this post. I bought the PS3 collector's edition with a gift card though, so it didn't actually cost me money. Agreed though, PC versions are a breeze to set up, and the higher resolutions are a nice bit of icing on the cake (Blood Money looks amazing at 1080p!)

I just beat Contracts today on PC. I love the Hitman games, and Contracts is really where it takes a step up to me. I loved Silent Assassin but the slow sneaking speed just kills it to me.

I didn't even like Blood Money on the Xbox. It was hard to get through windows, and there were texture issues. It's probably my favorite in the series on PC though. I've probably beaten it 10 times. And it does look beautiful on PC :)

On the picture it shows the PAL release.
Is there an NTSC version of this collection (for PC)?

There is no PAL/NTSC distinction for PC like there is for consoles. The collection will work regardless of the monitor plugged into the PC.
