My steam library has really grown in the past year! Now at nearly 2100 games. Patient gamer and bundle games sales have really helped push that figure along.
The latest additions have been from the Humble Australian Bushfire Relief Bundle. I've already cleared a number of games from that bundle.
I also retrieved keys allocated to my account on Humble Bundle because there is no guarantee that they will always have spare game keys - especially years after a bundle has been bought. I'll probably sell them to recoup costs.
