ajensen: I am at work and was about to buy This War of Mine when someone came to ask me a question. Didn't take long to answer it, but the game is gone! Should have hit buy right away, haha! Lesson learned... I'm on the lookout for it to reappear now.
Dgaart: I know some folks only like to buy on GOG because of the DRM free-ness and/or just to help support the awesome site. But you might consider signing up for Humble Monthly for a month, and then cancel. You automatically get This War of Mine and South Park:Stick of truth, then next month you will also get 4 more random games. Also, if you buy the $1 tier of Humble Jumbo Bundle 6 first (only available for about 30 more minutes) you also get 10% off humble monthly for a month. So basically. its about $11 for This War of Mine, South Park, ShadowRun: Boston Lockdown, Oceanhorn, Warmachine and 4 more games (which are usually pretty solid quality).... just sayin'.
Thanks for the suggestion! Though I do love to support GOG, this is definitely not the only place I buy games. I'd probably go for the deal you mentioned except that I already have South Park and a few games from the Humble Bundle too. I have been tempted in general by Humble Monthly, but I just own too many games that the risk is too great of getting doubles.
Thanks for the idea though, it is appreciated!
