edit:  Here's a badass screenshot haha:

hmm.... I'll consider tomorrow after I get paid.

It feels so good to finally have it sitting in My Games list...after waiting for two years...

Couldn't you pre-order it from Amazon for $38 not too long ago?  When did they get rid of that?

Don't remember that.

Either way, I want the Steam version for various reasons.

Also, the game will release worldwide on Steam on Nov. 18, so this preorder goes for anyone around the world.

I'll be buying the retail version... I have high hopes for this.

well, I'll skip the preorder because I don't know what the exchange rate until I pay the credit card, so it might be cheaper to buy it here in retail. see! you americans are screwing us international customers!! :P I won't be buying Peggle Nights because it may become VERY EXPENSIVE even for Peggle!

but I'll definetely get L4D (and Peggle Nights!)

Peggle's fun...I just have a problem paying for such a casual game haha. Even though I know it'd suck the life outta me.

I've been waiting for this for months. It's probably over a year now. I just don't have the money. I'll be getting this as soon as possible.

I'm definately going to get this just because its by Valve and they have never disappointed me with their FPSs.

I dont know much about this game other than the keywords ZOmbies and Co-op.
