Another insurgency key, works three times like the one above.

It's been used up, enjoy guys!

I have a 25% off coupon for pixel piracy if anyone wants it. Steam name tilmoph.

My Steam name is Schadrach42, I'm going to post a large number of steam keys in a spoiler below. Get 'em while they're hot, being openly posted means they'll get snapped up pretty quickly. If you're really appreciative, just PM or Steam gift/trade me anything I don't already have.

Enjoy and Happy holidays guys!

I also have the following on those Humble Bundle gift links. For everything below here, I have to ask for something in trade for these (mostly because it requires me to expend effort beyond posting this to give it to you), but I'm unlikely to be too picky, unless it's something truly terrible.

I also have the following in my Steam inventory. Most of these are tradeable, Contraption Maker is giftable only for 30 days, though:

Just bought a Saints Row IV key that turned out to be locked to the US(yeah, I wanted to save a small amount of money by going the Amazon-route instead of Steam :'C), so I'm looking to trade it for something of around equal value.
I'm not overly picky, but I already own a shitload of Steam games and I'm not very intrested in strategy, sport or indie games.

Once again, the key is region locked to the US, so only trade with me if you're from there.

I have Empire Total War for trade, if anyone is interested.

I have two Insurgency keys from a previous Humble Bundle that expire tomorrow. If anyone wants them, they're up for grabs:

[EDIT: All gone!]

Looking to trade a few games:

Super Street Fighter IV Arcade Edition steam key
The Swapper steam key
Nuclear Dawn steam key

Any of the final fantasy games or most other J/RPGs on steam (valk chronicles, ys, DA etc) I'll be interested in.

From the HotS betakey giveaway thread, because nobody seems to read my post there.
It's gone

leberkaese:
It seems like I can't read. I realized too late (after joining the contest) that these keys were only for NA region, but I'm from the EU. Now I've won one of the keys and can't use it.
PM me, if you're from NA and still need a key.

Keys for games from the current SE humblebundle that I know I won't play.

Supreme Commander 2; M3G20-G08BP-8T39K
Thief; KCWV8-5RA7Q-BKAR4
Murdered: Soul Suspect; JVJC6-EMNHN-V7F32

Deus Ex HR DE free up for grabs, just hit me up.

Startopia; 45BTT-C6WHG-42PZY
Kane & Lynch Collection; BK9N5-EI3FY-ND2MJ

Due to reasons of my laptop being a dick, I've now got a spare key for Kerbal Space Program from the Humble Bundle up for trade.

Game cost me about £13 so I'm hoping for something of similar value in return. Not too bothered about genre, just as long as it's not something I already own. If you've got any offers, feel free to PM me.

EDIT: Annnd, it's gone.
