It can't be traded in because it's free at the moment.
It will probably be possible to trade it in again in a few days / weeks as usual.

Titan Quest Gold (includes expansion) for $7.99 at Amazon (game is DRM-free) and tons of fun. (Better than Diablo-clone) ;)

Thanks for the link to the new free gmg game. Already have it on steam, but surely in the future it could be used to get more in-store credit on GMG ffor something else!

Whats that about trading in?

previously, the games on GMG that you got for free were able to be traded in for other games... in fact, you took 2 or 3 games for free and a couple of months later you had about 3-5$ in trade-in value. So you chose another game or DLC and gave them the free games back :)

Unfortunately, this game has been marked as "can't be traded in"

I see. It looks like they realised what people were doing.

GMG allows you to give a game back, this gives you credit for buying another game.

It's a nice feature for people who don't want to own the games they are playing. For others (e.g. collectors like me) it's pretty much useless - why would I want to rip a game out of my collection? ;)

edit: ninja'd ;)

why? because the client is the worst I have ever seen... I have collected the really cheap or free games, waited some time to trade them in for Steam Titles :)

I wonder if steam will ever get this option. or dare i say, GOG.

I hope so,I have a TONS of ugly game from bundles,never installed,I want to nuclearize from my account :l

BTW,Hacker Evolution for free on GMG

I think that trading in is a good idea, as the distributors get money back from used stuff. Plus i could get rid if games i dont want, and get stuff i would really like.

GOG can't really do that. If you allow trade-ins, then you have to make sure that the original owner of the game actually stops using it. With DRM-free games, you cannot do that.

Also, personally, I'm against trade-in options since they tend to increase the prices for the people who don't use it. I understand why such a service might seem useful to others, but for me, it'd only have disadvantages.

Valve says, no.

How do you tell if GMG sells the game or a steam key?

It's explicitly stated on the page, like here for instance.
