Help someone else out, maybe.
Kind of odd to advocate donations to someone else on a site you're trying to get donations for yourself on, but here we are. If you dug That Dragon, Cancer when I played it, but don't want to pay for the full game or don't think you'd be able to play it yourself, consider kicking them a dollar or two. The game's length and one-shot nature have led to Let's Plays putting a bit of a dent in their potential profits, which is only amplified by the game's niche appeal, and they deserve every bit of help they can get.
