Arcadius-8606: I had a small few bundles via HB.
* Humble Voxatron Debut
* Humble Indie Bundle X
* Humble NEOGEO 25th Anniversary Bundle
and all of their free giveaways from 2010 til recently. I also had a gifted copy of Skullgirls which came with the DRM-FREE version that is no longer available for purchase. Though it's no longer updated, I love this version of the game and it's easy to setup for local events and allows hot switching of gamepads on the fly.
I bought a few games direct as gifts for family and friends over the years.
I had a good time but I tapped out and deleted my account after all of this and other stuff. Over the years they would pull games or parts of games from their service with no warning. Games like Anodyne and Skullgirls lost their binaries or DRM-FREE status with no heads up.
All of my games are backed up. I gave away my Steam keys years ago.
Pretty sure I got the DRM-Free version of "Skullgirls" a while back there too. Is that not being sold there anymore or in general? Shame if that's the case.
