StingingVelvet: That language lends itself to the question of whether it will be sold here normally. I can't back the kickstarter at the moment due to my situation.
I was asking myself the same question when I saw this Facebook posting.
Some of you (okay, a lot of you) have been asking both Obsidian and GOG if there's any chance that we'll be able to bring the next game by the acclaimed creators behind Baldur's Gate 2, Planescape: Torment, and other remarkable PC gaming experiences to your favorite DRM-free gaming platform. GOG.com is thrilled to let you guys know that we're going to be working with the cool cats behind Project Eternity to distribute their upcoming title on GOG.com, completely DRM-free! The game will be available on GOG.com at the exact same time as it is on any other platform in the world, ready to download right to your PC.
What's that mean for you? Well, it means that eventually you'll be able to buy the game on GOG.com when it comes out, of course, but more importantly it means that if you back Obsidian's Kickstarter project at the $25 tier or higher, you'll receive a code to download the upcoming RPG from GOG.com. So go and check out the Kickstarter project--there are a ton of crazy rewards for pledging at levels from $25 up to $2500 and beyond.
Once you've checked out Project Eternity, you might be jonesing for some award-winning RPG goodness and then get sad that you can't play Project Eternity right now, dangit. That's understandable. Good news! You can pick up Baldur's Gate 2, Planescape: Torment, and all of the other games in our Diamonds of D&D sale, running from now until Friday, September 21 at AM 9:59 GMT.
In short: yes, you'll be able to buy the game from GOG.
