Did any of the GG games get revoked yet?

Maybe later, maybe won't, time will show.

For some reason when I checked GG earlier they gave me keys. If you gifted yourself a copy check your game library on GG

I bought two packs and they refunded me one pack and removed all of the two packs. Until now I still don't have either the game or my money.

It won't get revoked.

Stop being paranoid and don't be a fear monger.

Steam will only step in if GG can prove it's a case of fraud. In this case, NO ONE frauded them, no one stole from them.

They listed a price. You paid for it. You got your goods. Deal is over.

If, however, you HACKED into their server and stole a shit ton of CD keys then Steam will block those keys.
