What do you think was the best giveaway that EGS did?

For me it has to be that time where they gave away Rocksteady's Batman Arkham Trilogy+DLC all as one package. It's easily my favourite giveaway and I am shocked that something of that caliber was given away for free.

There are giveaways I regret ignoring (alan wake, talos principle, super meat boy, etc), but I'm so glad I didn't miss that one. I suppose it is pretty cheap to buy the collection nowadays, but in terms of quality and quantity, I don't think that giveaway can be topped.

What do you guys think was the best giveaway?
