Bought ravenswatch for 12.50, questioned why when I have so many humble bundle games

I've been a subscriber to humble choice since day 1.

I went back through the last 2 years of bundles (average about 1.5 activations per month) and added games to my account.

Next time I get the urge to buy something "because it's on sale" I'll go back and add things I've already paid for.
