This is a really difficult topic for us because we want the games available through as many portals as possible. Sometimes the licensor has issues with a particular distributor, it's rare but it does happen, and sometimes it's the distributor that has reservations on the type of game, and/or the suggested price of the game.
We're doing our best to get the Humongous titles on GOG. We follow the forum posts, and we receive a lot of messages on Facebook, Twitter, and email requesting DRM free releases, and we'll keep trying to bring them to you.
Thanks, obviously I appreciate the help. I apologize for some of the disparaging comments earlier; hopefully you can understand my severe disappointment thus far as the games appeared on Steam but not GOG.
I hope that you, GOG, and Tommo can work out some good bundle deals, 2-3 games for 9.99 each.
