Looks like I'll mail support or something, though I doubt the foot dragging is on GOG's end. There's been enough GOG second classing by the Team Steam kids that I doubt it's always an unfortunate coincidence.
Yeah, I'm suspicious that this is just buck-passing. Someone on the Obs boards said they messaged inXile and was told it was in Obsidian's hands. This was before Brother None popped in and laid it at GOG's feet.
I'm a bit miffed at the whole issue. Just because I want to get the game on my preferred platform, I shouldn't be stuck sitting here twiddling my thumbs and wondering how the Steam community is enjoying the game. Sick of GOG supporters being treated like the red-headed stepchild. There's no reason on earth why they can set up Steam keys but don't have their shit wired down enough to have the GOG keys ready to go at the same time.
