Now that Valve has introduced a new system for trading Steam games and TF2 Items (look here!), I have taken it upon myself to create a thread for the inevitable Have // Want's that will soon be filling up the forums.  I'll start: 
 
Have: http://steamcommunity.com/id/Rockdalf/inventory 
 
Want: Deus Ex:  Human Revolution 
 
EDIT:  Valve FAQ

So your gonna trade TF2 items for video games? 

If anyone has an extra copy of Half life 2 ep 1 id be happy to take it off your hands! 

How does this even work?

I have a spare copy of Sanctum if anyone wants to trade. Go watch the quicklook. It's a lot of fun.

Here's my TF2 items link: http://steamcommunity.com/id/beefygrandmole/inventory

If someone wants to trade any for a game i'd be happy :)

I have a copy of portal I'm good to trade away for something cool  
 
Also here's my backpack

And my Steam profile

I have a spare copy of Sanctum if anyone wants to trade. Go watch the quicklook. It's a lot of fun.

If this takes off I'm gonna have to start buying Steam sale games in multiples.

What are you looking to get for it?

Inventory

Definitely not Team Fortress items. Sorry. I am looking for a game trade, but there are plenty of cheap games I want that people might already have a giftable copy of.

Didn't realize they were only gifts, not games..forget the trades for now that I had open.

@Rockdalf: I'll give you a copy of spiral knights for your headtaker 

I'm pretty sure I don't have any worthwhile items, but if someone wants to offer a game I don't own for an item I have:

http://steamcommunity.com/id/Winsord/inventory/

http://steamcommunity.com/id/Cloudenvy/inventory/

Taking game offers!

My Inventory

My Game List

If you see any games you'd like, make me an offer of something I don't have in a PM. I'm not too picky, just something roughly the same price range.

Edit: Since my available games aren't showing up in the inventory now for some reason, here's what I've got to offer:

• Amnesia
• Borderlands DLC: Mad Moxxi's Underdome Riot
• Cogs
• Killing Floor
• Puzzle Agent
• Rush

Might as well toss my hat in 
 
Anything worth wile?  

I think you should put a link to the Official FAQ in the OP just so people aren't confused. You can only trade gifts that haven't been opened (attached to your account).

Have:
Half Life 2
Half Life 2 + Half Life 2: Lost Coast (both games included)
Half Life 2: Episode 1 (x2)
Half Life 2: Episode 2
Half Life 2: Deathmatch
Portal
Portal 2
Team Fortress 2
Super Meat Boy
Cogs

Want: Troublemaker's Tossle Cap, Bonk Boy, Bombing Run, Honcho's Headgear, Fancy Dress Uniform, Lord Cochwain's Novelty Mutton Chops and Pipe, Brigade Helm, Respectless Rubber Glove, Sight for Sore Eyes, Security Shades, Teddy Roosebelt‎, Googly Gazer, Prairie Heel Biters, Ze Goggles, Bill's Hat, Buds, Gentle Manne's Service Medal, Metal, or Keys.
I also want Bastion so if anyone has that I'd trade one of the ~$15 games for it.

Make me an offer. Also, looking for strange weapons. Here's my inventory.

My TF2 backpack

I have a cow mangler to trade if anyone wants it.

My Games

I would really like a copy of Street Fighter Arcade Edition if anyone wants to trade that.

PM me on Steam or Bomb if you want something.
